I've been finishing up work on a design for some H2C inductive hotend modules for my H2S/H2D case, as well as a few updates to the base design.  The updates will include a new gasket, and some snap in latch parts (which will remove the need for four odd sized M3 screws).  I may be adding a P2S option as well, but I don't own that printer, so will need help from the community to see that design though.  The H2C update though is completed, and just needs to be fully test printed (so I can add one more Bambu spares case to my growing stack of spares cases :D

The pics below show some of the latest CAD models for the update, and some test parts I printed to verify the fit and function of the new snap in latch parts, and the H2C inductive hotend holders.  The inductive hotend holders will require one 6x3 cylinder magnet per hotend (though those are also required for the existing H2D/H2S design as well).

I treated myself to an H2C for Christmas, and just got around to setting it up yesterday.  The sucker weighs quite a bit, so I had to remember to "lift with your legs", but really it should be a 2 person lift to be safe.  Setup took a while to run though the calibrations, but so far it has been running pretty well.  I've not run any multicolor prints yet, but having a stash of ready to go nozzles in different sizes is really cool (even for single color).  But one thing I noted is that, despite having a pretty good sized filter, I can still smell the melted plastic when it's running certain materials (like wood PLA).  Based on the pics I've seen, it looks like the fliter either moves up and down, or there may be a door that blocks the bypass air.  I suspect the issue is that air can bypass the filter, due to the design of the exhaust system which has to do double duty as a filtered exhaust and recirculating filter (when running the heater).  I'd like to find a video which shows how the system works in detail (if I do, I will post a link).  It's a shame though, since it has a really big HEPA filter, with carbon, and the printer is much better sealed than the X1C (unfortunately it seems it's not as well sealed in the exhaust path through the filter).

The H2C is just a tad big for my current enclosure, (though I may still cram it in there), so I thought about bringing back an old (stalled) project which I never felt was tested enough to release.  It's an inline booster fan, designed to draw out fumes from the X1C (or any enclosed printer with the right adapter).  It should work with the H2C, and help pull the fumes out the back of the printer, where the exhaust is vented.  It may also help remove any air that slips by during the recirculation filtering too.

I was gonna work up an exhuast adapter, but found a really cool exhaust duct by Clough42 on MakerWorld, which is designed for the H2 series.  He kindly provided the STEP, so I reworked it just a bit to fit my existing hose couplers, and increased the standoff distance by 10mm to clear the poop chute (since it will bend to the left side of the printer).  I'm printing the adapter currently, and will need to order some screws to mount it.  The plan is to run a short hose from the adapter, over to an inline booster fan, and then duct it from there, out an unused doggie door.  Once I get the fume situation settled, at least for a while, I can get down to really using the H2C.  I also plan to (finally) release the remixed duct, along with my booster fan design, the hose couplers, and doggie door adapter, once I've got everyting running and tested (if it works well enough).  I've got a spares case update planned for it, and some other projects, where it should really shine with it's multimaterial capability.

It don't look like much, but I hope the above design (or something similar), will save a few hardware headaches for people building my cases (eventually).  One of the most common criticisms of my cases is that they require too much hardware (in the form of various M3 screws).  While I am of the opinion that hardware has a place in 3D printed designs, I think this is one area where I could improve things.  The above is a pic of a test sample which I am investigating, to see if it will work as well as using a screw to secure the part.  If it works, I may drop the screw requirement for this part and it's opposite latch cleat on the case, in favor of a clip in design.  It's still early though, and I may need to make more changes to the design to insure there is no creep of the parts when the latch pressure is applied, but if I can get it to work, it will save using two of the more oddball M3 screws (per latch), which have been required to build the cases.

If these clip in latch inserts work out, they will probably be first seen in a fully revamped 8x watch case, which I've been working on.  That 8x watch case is similar to an earlier prototype which I had completed (though never published), and will have all the latest updates which have already been applied to my other cases, which can be found at the links below).

12/13/2025:  I got stuck with a side quest for the past week, due to some events outside of my control.  I'm still wrapping that other projects up, but will hopefully get back to this one.  I don't expect it will be done before Christmas though (the holidays are busy and stressful enough, without extra deadlines to chase). 

I saw this design today, which is a label that can be attached to a jumper cable, and acts as a reminder of the order of connection and disconnection.  I don't use jumpers that often, but everyone in my family has a pair in their car, so it's handy to have something that may help with setting them up.  The design is simple, and although I really like the original, the raised text is something I try to avoid on parts, since it can get knocked off with any abuse.  Raised text also does not tend to look as clean as inlayed text does.  Since I wanted to make some of the labels to give out to family members who will be in town soon, I made my own version (pictured), which has inlayed text and some other changes.  I don't plan to release my version for a while at least (if I do it will probably a month or two).  I suggested these same changes to the original designer, so maybe their design will be updated with the same changes, which I think will make them more durable.

I think I first need to soften a bit of what I said in the last post regarding my dislike of Printables (for technical reasons), since the community over there is awesome.  Somebody suggested that the 20bin Gridfinity case could maybe use a diet, and my initial reaction was that it would be a lot of work for a little gain (it is lol).  But after considering it, and looking closer at the model (which I have not done in almost a year), I agree, it needs a diet.  I did something similar with the 16 Bin Gridfinity case over a year ago, and it turned out well. 

I was already gonna revisit the 20 bin design anyway, since the same person mentioned they experienced a crack where the latch connects to the case, which has been a rare problem on the older case designs.  That problem had been resolved with some longer latch parts (I thought), but I now have a better fix for that problem, which has been successfully used on several similar case designs.  The update will include the fix, along with possibly some other goodies.

So I got to work on the 20 bin case update, and I spent several hours yesterday and today on an almost ground up rework of the design, having trimmed a substantial amount of material from it.  As sometimes happens though, just when I thought I was done, I noticed something that has really thrown a monkey in the wrench.  I'll have to rework the gasket design again, and possibly a bit more, which will likely involve several more hours of work.  But I'm planning to fix it, just not today.  

I'm not really sure yet how much material and time this update will save for folks printing it, but I expect it will save a few plastic trees in the long run.  I also like that it has a bit of a compact look.  I'm planning to release these with a 6U, 9U, 12U and 15U deep base, with an optional gasket.  I don't know yet if these will get a funky design or pattern like the "Generic Printer Spare Parts Case", but if things go smoothly (unlikely lol), that is a possibility.

10/28/2025:  I spent another hour or so on this design, and I think the gasket problem should be sorted out.  I'm starting a test print of a 6U case with the gasket option, to test things out.

10/29/2025:  Just a bit of progress to note on the prototype case design.  The lid has been printed, and I'm printing a base now.  In comparison to the current design, the update should trim it down by a good bit (though I have not checked how much yet).  I think I will end up needing to print two prototype cases though, since I will also need to test the version without a gasket.  In the pics below, the new lid is placed on top of the current version case (with the lid set so it aligns with the top right edge of the current case design).

10/31/2025: I've got the prototypes printed, and one is fully assembled (aside from the TPU gasket).  The 2nd prototype is a 9U version, without a gasket, and it has yet to be assembled.  So far things look good for this update.  I recently saw a video by Maker's Muse, where he was testing several flexible filaments to make wheels for his battle bots.  One of them looked really interesting, as a possible material I could use for a gasket with these cases.  I'm checking with the company that makes the filament, to see if I can get a small sample to test with, which would allow me to make one or two gaskets.  The TPU Air is much more flexible and compressible than normal TPU, so I expect it could work well, though I may need to modify the gasket design slightly for it.  If I can get a sample, and it tests well compared to normal TPU for the gasket, I will likely provide a gasket design for the case that can be used with the compressible TPU Air, and another gasket design that would work with standard TPU.  I will post some progress pics of the prototype cases soon. 

11/3/2025:  The prototypes are completed and based on them, I made some very small changes to the final design, including moving the handle on the larger cases, so it balances better.  The gasket works well, though I have not dunk tested it yet - but I don't expect it to be "water proof" anyway.  I've not heard back from Siraya Tech about a small sample of the TPU Air, so I don't expect to modify the gasket for that material (as an option), and will likely release the design with the "standard" TPU gasket design.  Below are some pics of the prototypes.  They are a 6U and 9U version of the case (there will also be a 12U and 15U version included in the profile).  I now need to build up the rest of the 3mf profile, with the other sizes of cases. 

11/5/2025:  I heard back from Siraya Tech, and they offered some very helpful info regarding the gasket material.  It seems the foaming TPU Air is not as good a choice for gaskets, compared to other materials (due to chemical resistance and sealing capability).  They suggested standard TPU or PEBA as a good option, which I may try in the future if I get the opportunity.  Based on the Maker's Muse video, I expect PEBA would work better than TPU.  For now, I think I'm gonna stick with the plan, and with TPU 95A, which also means I don't need to tweak the gasket design further.  I'm still working through the 3mf profile, which will be rather large due to all the options, and I hope to have things ready this weekend.  I also need to do a dunk test of the case which has the gasket, though I don't expect it to do better than my other similar cases with the same gasket type (that is, it will be water resistant, but not water proof).

The 3mf profile is about done now, so I just need to work on updating the description and other things before it's posted.  This update will be posted to MakerWorld, but I plan to leave the prior version on Printables a while, for folks who may need spares for that design.

11/8/2025:  I just uploaded the new design to MakerWorld. The updated design is slimmer, and trims about 14% off the material requirement for a 6U tall case, compared with the v2.3 case. You can find it at the link below:

I used to upload most designs to Printables first, and then import them over to MakerWorld, but for some reason I stopped doing that a while back.  I went to upload a design to Printables today, and the reason for the change came roaring back into my memory.  There is a very arbitrary spam filter on Printables, which makes everything a huge pain when it triggers (the red text at the bottom of the image).  The description I'm trying to write (starting from scratch for the 2nd time), was about 90% saved as a draft seemingly without an issue, but then after I added the last bit (which is just a generic footer I add to all my designs there), it coughed up a furball and won't let me save it.  So I yanked out the bottom quarter of the description - and that didn't work, so I ripped out some more (nope), and now I am well past the point where it had been saving correctly previously, and it still says "spam".  I've wasted over an hour with this BS getting nowhere, so finally emailed them to ask what is going on?  There is not a curse word in sight (aside from "Bambu" lol).  I had a link to MakerWorld for a model which I referenced, which has some parts that are compatible - but even removing that also did not satisfy the spam filter.  This was my 2nd attempt to get the description added, and I think I'm gonna cut bait and set it aside for the day.  But I will try to do it over tomorrow - one more time.  If it fails again, then it was not to be, and will just put it on MakerWorld, where their spam filter is not as unpredictable.

10/10/2025: Well I have no idea what is going on with their crazy spam filter, it choked on the following text:

"Although this model is not remixable due to the license, I will upload some remixable models for the large and smaller insert modules (which install in the base of the case) as a separate design, and will link those here when they are available."

When I removed that section, the draft description saved, but when I put it back it choked with the "spam" warning.  At least I know they are not blocking the makerworld links or "bambu", but it's still damn frustrating trying to use the site.  I have a suspicion that their "spam" warning may actually be a max character warning which is poorly worded, since the description is rather long, with a lot of images to help with assembling the case.  But now that the description passes the "spam" check, I don't feel like testing that out further.

However, once the "spam" hurdle was jumped, I then found that my 3mf profile, which I had to generate from scratch in Orca, seems to not work when I download it from Printables (see pic).  The original works just fine though.  I've resaved the file several times, rechecked the original, and re-uploaded it, but every time it will not open with the "Loading of model file failed" error.  This was after completely re-working the 3mf profile from scratch in Orca (I just imported the geometry only from the original Bambu Studio 3mf).  I've spent several hours trying to get this design uploaded, and verifying the profile after downloading, but with zero success.  I'm setting this one aside again for a couple days.

10/11/2025:  Success! After another round of re-uploading and verifying, I can see that the 3mf profile made it through the process without getting corrupted.  You can find it at the link below:

I spent a couple hours today updating the last (unpublished) version of my "Generic Printer" spares case to the same spec as the Bambu X1/P1 spares case.  It had to be done in order to get the "Generic Printer" spares case closer to being released.  The updates were primarily to the base of the case, and will add cross compatibility with the larger bins (between the "Generic Printer" case design and the existing X1/P1 case designs).  That will also allow the use of some of the Bambu hotend holders in place of the bins, for users who use that type of hotend.  I don't currently plan other hotend holders for the case, but the blank modules will be available for remixing, when it is posted.  The image below shows the current 3mf layout.  I will need to test print the base again, as well as the bins (even though I already have a working case of the older design)

10/7/2025:  False start - Removed the link so I can update the design without any logos (hence the "Generic Case" name which I will probably need to change).  Once the model is cleaned up, it will be uploaded to printables instead of MakerWorld.

​10/11/2025:  Success! I had to fight with Printables site to get the description to pass their crazy "spam" filter, and then to get the 3mf profile to work (really odd problem where the profile would work in Orca, but when I uploaded and re-downloaded it, it failed).  Anyway, you can find it at the link below:

I saw that MakerWorld has a contest to design a cover for the new Ecoflow Rapid Pro X 300w power bank.  It looks pretty cool, and I had an idea for a cover that can be used to mount it to a Skådis pegboard (or wall mount it).  The design is completed (I hope), and I'm printing a prototype now, to test the fit.  I'll post some more pics when it's done, with a link to the design over on MakerWorld.

​I decided to go for broke with the tree supports on this one, since it's something I may never use (unless I win the contest lol), But I didn't want to have to reprint it, should something fail with the print due to a missing bit of support.  The cover for the Rapid Pro X is a bit challenging to print too.  It really doesn't have a good edge to use as the base for printing, unless it were set on it's back, and then the strength would be compromised.  I had to trim a fraction of a mm from one edge to get it to print without an "unsupported cantilever" warning in the slicer, and with some brim, it seems to be doing OK.  Once this plate is done, I will need to print a dummy model of the Rapid Pro X, to test the fit with the cover design and mount (and that is a 4-5h print by itself).

​

9/4/2025:  I just posted my entry into the MakerWorld "Power Meets Creativity" Design Contest, which is promoting the new EcoFlow Rapid Pro X power bank (which will be released soon).  Below is the link to the design if you want to check it out.

https://makerworld.com/en/models/1764814-ecoflow-rapid-pro-x-wall-or-skadis-mount-cover#profileId-1877952

The design was pretty much completed a couple days ago, but as always the "nice to haves" and the "just one more things" conspired against me, and it took longer to test and complete.  I ended up burning the better part of a spool to test the changes, but I'm happy with the end result, even if I may never actually use it.  Below are some pics from the various prototypes in no particular order.  The first pic though, is my box of prototype scraps, which is missing a few parts that ended up in the trash after I decided to do something different with the design.

I received an email from Bambu for a refer a friend promotion where they give the friend a 9% discount on a printer, and Bambu will send a 3-6% gift card to me as well.  It's a pretty decent promotion for everyone involved.  Unfortunately I don't know anyone in the market for a 3D printer right now, so I thought I would offer it to any of my Internet "friends" who visit this site.

I will send the referral link to the first person to send me an Private Message on MakerWorld, who asks for the link.

According to the terms of the referral program, the referral discount applies to most of their printers and printer combos such as the X1C, P1S, A1 and A1 Mini, and combos. 

HOWEVER, the referral discount does NOT apply to the H2D, H2S or P1P printers (or the H2D, H2S and P1P combos).  It also does not apply to the X1E (their enterprise version of the X1), which is only sold through their partner channels, as far as I know.

They only gave one referral code to me, though I think they may send another if the first one gets used (but I heard they are limited). 

Bambu has several stipulations for the referral discount program, which you can read all about in their terms here:

https://us.store.bambulab.com/policy/pages/referral-policy

Based on my reading of the terms (and I am not a lawyer), some of the highlights are:

• Once the referral link is claimed, it cannot be re-used, even if the first person to claim it decides not to purchase a printer with the link within 7 days of activating the offer. 
• The referral link they sent me is for their US store only. 
• The 9% discount can not be stacked with any other discounts (such as the $10 off they offer for new customers). 
• The referee (that is the person using the referral code) must be 18 years or older.
• Once the referral link is claimed, it is good for only 7 days.
• The referral discount is only valid on X1C, P1S, A1 and A1 Mini printers, and printer combos (not the H2D or H2S).
• Each order can apply only one referral discount code, and it can be used for the purchase of only one 3D printer. 
• Program Ends at: 2025/09/30 22:00 (Beijing Time, UTC+8)
  

I cannot make any guarantees that the code will work for any particular order, since Bambu has full discretion on that.  So if the referral discount link does not work when checking out for some reason, I will not be able to assist.  Please read the terms of their offer to make sure it will work for you, before considering requesting the referral discount link.  

So after reading all that, if you are looking to buy a Bambu printer, and would like to get the 9% off referral link (while also supporting this site, and my various 3D printing adventures at the same time), just send me a private message over on MakerWorld.  I only have the one code right now, so the referral link will be given to the first of my US based Internet "friends" out there, who send me a private message requesting the referral on MakerWorld:

https://makerworld.com/en/@mystoopidstuff

Just say "Hey buddy, can you send me the referral link for the US store?" or something like that :D

The button to private message is right next to the "Follow" button, over on MakerWorld on the left side of my profile page (which is also linked above):

I will try and check my PM's at least once a day. Once I've given my one and only referral link to a "friend", I will update this post that it has been claimed.

Thanks, and ​Happy Printing!

As of 9/7/2025 I still have a referral link to give out, for 9% off one of the printers in the promotion.

I've seen other makers who I greatly admire, organizing their workspaces with Ikea Skådis pegboards, but hadn't had time or the inclination to attempt to try and organize my workspace in a similar way, until recently.  I'm trying to break the old habit of confusing "storage" with "organization", since I've realized (too late), that putting stuff in drawers is the surest way to forget where it is when I need it.  The beauty of using pegboards, is that it's hard to forget where something is, when it's staring me in the face.  I recently posted about how I made some Skådis pegboards and mounts, and after installing them, I decided to make some bins, drawers and tool holders for my stuff.  Most of the things I'm using are stuff I made, but there are a couple that were remixed as well.  I also found some cool designs which fit some of my tools (specifically holders for the IWISS tool holders by Reitangle over on Printables). 

Currently I've filled up two pegboards with bins, drawers, holders and tools, and have a new project for adding one to a kitchen.  I'm not sure when these will get posted or how, but I think this is gonna be an ongoing side project for a while at least.

8/30/2025: There were a couple designs which I previously had taped to a cabinet with 3M Command Strips, but needed to move over to a Skådis pegboard which was going to be placed in the same location, so I reworked them a bit.  These have not been updated with the changes, but the model for the label dispenser can be found on MakerWorld.  I guess I have not posted the Equal holder though, so will add that to the growing list of stuff to do.  I also designed a sharpie holder, which holds 2 pens, but did not grab a good pic of that one.

I'm also working on the drawers.  The base design is completed, but I decided it would be cool to have handles which can be printed separately (in a different color), or even customized.  The handles will also help to lock in the labels, though they stay in well enough regardless of a handle being installed or not.  The handles will require a bit more work to add to all the types and sizes of drawers I've designed so far, but I first need to fully test the fit of them.  The last pic below shows one of the latest prototype drawers with the separate handle.

9/5/2025:  I feel the general design for the Skådis drawers is complete, but I have not yet posted it.  The one issue with the drawers is making printed labels for them.  Using the slicer can be a bit tricky, since it lacks tools to align text, and adding text from a CAD app is even more of a challenge when there are many labels to make.  That is why I'm now looking at simplifying the labels into a template that would would with the MakerWorld (MakerLab actually) "Make My Sign" tool.  I've used that tool in the past to make some name plates for a symposium, and it worked out really well.  The workflow for those included merging the generated nameplates with a custom model for a nameplate, but for these labels, I think everything can be done within the MakerLab tool.  I'm currently running some tests to proof this out, and if it works well, I should be able to create the four templates required to fit all the different drawer sizes.  Then it will just be a matter of sharing the template when I post the drawers, and then folks can easily create nameplates using the "Make My Sign" tool.  

​Something that was a bit problematic with this process however, is that my CAD program will not properly export 2D shapes as a single "path" when exporting to .SVG.  It instead dumps a bunch of "polyline" statements into the .svg it exports.  It is also missing the "viewBox" parameter.  The "Make My Sign" tool does not like that, which is understandable, since the polylines do not create a closed path.  And since my exported .SVG files were not a single continuous "path", I was failing to import my svg's as a baseplate in the "Make My Sign" tool. 

​The fix was to export the shapes as an STL, then import that STL into TinkerCAD, and then export the STL as an SVG from TinkerCAD.  Thanks to Xombieparts over on Reddit for the suggestion to use TinkerCAD to export to SVG.  

The other, and much smaller issue, was that when importing the .svg into MakerWorld, the dimensions get scaled to about 4/3rds of the original, and need to be rescaled based on the actual dimensions.  This is not a huge problem, but something I need to be mindful of when setting up the templates.  My first test print of a label was about 10mm too narrow to fit the drawer, but I think I may have it properly sized now, and am running a second test print for a label using the "Make My Sign" tool.

9/6/2025:  Now that the process to get a working SVG file has been sorted out, I went ahead and created "Make My Sign" templates over on MakerWorld, for all the bins and drawers which I've designed so far.  I'm testing some of them now.  I think using the "Make My Sign" tool will be a big time saver for making printed labels, and fortunately there wasn't much that needed to be changed in the design.
