The MiniBFS v1.3, which is designed to be printed on an A1 Mini or Prusa Mini size printer, was always intended to be customizable, but when I originally released it, I did not include the customizable insert module.  Today I updated the MiniBFS v1.3 files to include a modular base and lid option (with screw posts to install a custom module insert), and added a separate model of the inserts, which include STL and STEP models.  I had to post the separate design for the module inserts because I want to keep the MiniBFS models under the Standard Digital License (which does not allow remixing), but I want the insert modules (which work with the MiniBFS) to be customizable and remixable.  To do that, I released the insert modules (only) under the  CC BY-NC-SA 4.0, which does allow for remixing.

I hope that posting the insert modules will not lead to confusion for folks who just want to build the MiniBFS v1.3.  I added info to the description better describe the lid and base parts which are included, and make it clear that the "MODULAR" base and lids were only to be used with the customizable inserts (which are blank).  It would be cool to see a remixed base module to hold Prusa Mini tools similar to the A1/A1 Mini Spares case (which I cannot create since I don't own a Prusa Mini). 

There are a couple small updates to the Bambu X1C/P1P/P1S and A1 spares cases, to optimize a couple things based on feedback.

The X1C case will get revised hot end holder modules, which will unfortunately require a small change to the base (so they will not be backwards compatible).  It will also get the tabbed compartment latches.  I'm testing the changes now, although I won't be using them myself (since the changes are small, I am testing cut down test parts to save on materials).

The A1 case will get a slightly (1mm) longer pocket for the small hex wrench, and also a revision to the grippers which help hold the needle tube.  

Thanks to the great feedback on these designs, which has been very helpful to improve them!  I decided to move these to the top of the queue since they are existing designs, but the other stuff like the Gridfinity watch cases, the Bento clone and other stuff is still being worked on, tested, or just requires a build guide.

Somebody asked on Reddit a while back, if they should scale Gridfinity to work with an Ikea Alex, and I suggested that they would be throwing away the key benefit of the system (interchangeability of bins).  It did not occur to me at the time, but I use a non-standard system for my Alex drawers almost every day (though it's not Gridfinity based).  That revelation popped into my head while I was going through some of my old designs, and realized that I never posted one for an Ikea Alex drawer organizer.  I designed it back in late 2021, but it seemed to get abandoned (sorry, it happens).  It may have been dropped because I started working on something else, or possibly I thought there was something better out there.  I mentioned at the time that Thingiverse was having problems, and I recall that some of those issues resulted in the frustrating loss of all my work as I was attempting to post a design there (though I don't recall which design that happened to).  Anyway, I don't recall why it was not posted, probably I just got busy.  

The organizer is based on a 58mm cube size, so they are rather large, but they fill the Alex drawers up, and use 50 or 100mm tall bins.  I also noticed that a 4x4 Gridfinity grid fits within a 3x3 grid of the 58mm based system with 6mm to spare, so it seems possible to make a bit of a hybrid system, or a drop in Gridfinity adapter for a 3x3 to 4x4 grid.  An adapter would waste 3mm of space all the way around the 4x4 Gridfinity grid however (about 7% of the area), but it could be worth it.  

I don't mind prepping the files and posting the models, but before I consider that, I'm questioning if it's worthwhile. With Gridfinity out there, all other "systems" seem redundant.  And I have to bet that in the almost 3y since I made mine, there must be something better out there for Alex drawer organizers.  I'm gonna poke around Printables and Thiniverse to see what's out there before I spend the time to organize the bins and set up the files to post.  I don't know if the world needs another grid-bin system (Gridfinity is really the best out there).

Update 8/1/2024:  Thanks to everyone who participated in the poll!  I think this project will go ahead, but a bit differently than before.

I was looking at the design today and thought, "why not just build these with the same standard dimensions as Gridfinity, but larger?"  And then I recalled reading about a tool which generates bins of any size using the Gridfinity standard dimensions, I just had to find it - and after a quick search, I did!

For an Ikea Alex, the base unit would be 57.8mm to fill up a drawer with a 5x9 grid.  The bins could be 4, 8 and 16U tall, and  generated using this online generator (https://gridfinity.perplexinglabs.com/). The tool also generates base grids, however to fit the Alex drawer tightly, the grid base needs to be just a tad larger.  The base also has to be split to print on most printers, so all I'd need to upload is the base grid.  That greatly simplifies, things and makes it much easier if I decide later to make some lidded bins in the larger sizes. 

So I think what I will do, is model and test a split up base grid (57.8x57.8mm) (almost done), and then I'll print some of the generated bins to test.  If they work, then I may also make an adapter plate that will take the larger 3x3 grid, and convert it to a 4x4 grid of 42x42mm standard Gridfinity bins.  They adapter would allow for using either type of bins (the 57.8mm base or the standard 42mm base bins), but still fill up the entire Ikea Alex drawer.

Update 8/2/2024: I thought I had the base grid completed, along with the Gridfinity adapter.  But I noticed when I was generating some 57.8x57.8mm bins using the online generator (https://gridfinity.perplexinglabs.com/) that the bins were not coming out as expected when using the "Gridfinity Rebuilt" option.  I instead tried the "Gridfinity Extended" option and those were the right base grid size, however they did not match up when I tried them with my models (they are about 0.5mm narrower in the base plate).  I am using (or I should say I thought I was using) the spec here and here.  I think the "Gridfinity Extended" bins will still work, but I need to print a few to verify.  I found the issue with my base grid though, and somewhere along the line I needed to bring in the base pocket walls by 0.25mm.  I'm probably gonna re-work my base grid, but since I printed a few of them, I'm gonna test with a generated "Gridfinity Extended" bin first, and see how loose they actually are.

Update 8/3/2024: After finding the 0.5mm error in the first iteration of the base grids, I decided to just copy what works.  Since the plan here is to just upload the base grid for an Ikea Alex drawer (with a grid size of 57.8mm), and then use the Gridfinity generator at https://gridfinity.perplexinglabs.com/ to create the bins, that is where I started.  I downloaded a "Gridfinity Extended" base grid and bin using the 57.8mm base grid size, and then copied those dimensions to build the Ikea Alex base grid, and the standard Gridfinity adapter.  The pics below show the result, and look a lot like the ones above, but trust me, they are completely rebuilt.  I also included a screencap from the Gridfiity Generator, showing the setting I use for the compatible bins.  I'm running a few of these off to make sure things work, so it's not yet ready to be posted.

Update 9/3/2024:  Well its been a month, so I thought I should get back to this one.  The one issue I had with the setup so far is that the gridfinity adapter can be hard to get out when I need to access the bins at the rear of the drawer.  Access to the rear bins in a drawer like this is always gonna be a hassle if they are stacked, so that is what it is.  But I thought that if I added some handles to the adapter, the whole thing could be lifted out for better access.  The adapter should hold up to 16 gridfinity units, with a 19U height in total (my bins only go to 18U total).  I'm currently test printing the new adapter, and hopefully that will be the last part to this setup that I need to make for a while.  

I had considered making some lidded bins for the larger 57.8mm base grids, however that is a considerable amount of work, and with the adapters, the standard gridfinity lidded bins could be used anyway.  

I only have a few watches, with a few Seiko's and some Chinese watches (which are surprisingly good).  But a while back, somebody suggested a larger watch case similar to my single and triple watch case designs.  That idea has been bouncing around in the back of my mind recently, and since I was looking for another gridfinity project, I decided to see what I could make.  I used my 20 Bin Gridfinity Box For Stuff as a basis, and outfitted the cases with upper and lower TPU bumpers, to give the watches a bit more protection.  Currently these designs only exist in CAD, but I plan to test them out when I have the time.  

I'm also considering a new design for the watch holders.  The current design, which is a remix, works pretty well for watches with leather or cloth bands, but not as well for watches with metal bracelets.  The new design is not yet laid out however, so it will be a while.

Update 7/10//2024: I haven't printed these cases yet, since I really don't need them.  They will probably get tested sometime soon, but it's hard to waste filament on stuff like this (that I'll probably not use).  I should probably start an Etsy store to sell my prototypes, so they could at least get a good home.  

In the meantime (while I'm not printing this case), I was able to come up with a design for a more universally useful watch holder.  The current design does not work well with watches that have bracelets, since there is very little adjustment (it works fine for watches with cloth or leather bands though).  So I had this idea for a TPU holder, that could flex a bit and help hold watches where the band or bracelet is a set size.  I need to test this, but I think it will look something like this (the one on the left in the 2nd pic):

Update 7/30/2024: The 8x case is printed and works well.  I really like the way the new TPU and PETG watch holders work with a bracelet band too.  The TPU liner took several iterations to get just right, but I think it should be pretty universal now.  The watch case was printed using Elegoo Peacock Blue PLA with an inlay of Polymaker Galaxy Blue Polylite PLA, and the base is Duramic Gray PLA.  The Orange bits were done using ESun Orange PETG, and the flexible inserts were done in White Overture 95A TPU.  I think the filaments printed really well, though I initially had some bad stringing with the TPU (even after drying), but the fix was to turn on "avoid crossing wall" under General > Quality > Advanced in Bambu Studio.  I also slowed down the Max Volumetric Speed for the material, which also helped (but increased the print time for the TPU parts).  The 4x case has not yet been test printed, but I don't expect any issues with it, since it shares many dimensions with the 8x case.

Most of the watches shown are Seiko or Omega "homage" watches from AliExpress, and are really quite nice.  The Seiko "Captain Willard" homage watch which is shown on a bracelet is from ADDIESDIVE, and sports a Seiko NH35 automatic movement.  It runs about $85, which is not a bad deal for such a nice watch.

Update 8/8/2024:  The watch holder has been uploaded to MakerWorld and Printables.

The cases have not yet been uploaded, those will take some more time (I have not yet printed the 4x version).

After seeing Mici's universal labels, it got me thinking that that my large lidded bins (2x, 3x and 4x versions) don't have any integrated labels.  I found that I could use the grids on the large bins to add some label "chips" which could be edited in the slicer to add text.  This is not a perfect solution for all the bins, since it only works with the bins that have grids, but I like it.  The labels can be changed out by simply loosening the grids and swapping the chips.  I linked the chips together to make them easier to print and keep track of when installing, but they could be unlinked and installed separately.  

To assist with adding the text modifiers to the labels (using Bambu Studio), I also made an animation (below) which goes through the steps.  The individual frames are also included below.

I'm still testing this update, but when it is ready, I will post links to the updated models.
