I'm Working on an H2C and P2S Case (Maybe)

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).

11/17/2026:  Progress is still ongoing with this update, but has been slowed down due to another project that has taken longer than expected.  It's still on track though, and I'm planning to add a few new features, which will reduce the BOM further.  The plan / hope is that the case will be buildable using only M3 SHCS screws, of just a few sizes (as well as some magnets for the hotend holders). 

I've had some great help and suggestions from community members as well, which is improving the ideas for the next update.

I expect that my other project will be completed this weekend, and this will be the next thing up to the (build) plate.

11/22/2026:  Small update, but I think it will be the last one before I print this case to test it out.  There are several new patterns I'm considering for the outside of the case, and I think I can get rid of some more of the odd types of screws that are in the BOM currently.  The m3x6 BHCS will no longer be needed for the latches inside the case, which now snap together (pictured).  These new latches will get rolled out to several other designs as well, but it will take some time (there are probably a half dozen or more designs that will need to be updated).  There are some m3 FHCS which will also be removed from the BOM on the H2 Case, so all the screws needed to make the cases will be m3 SHCS (of a few different lengths).

2/2/2026:  This project is still going, but my boost fan / window vent project is taking priority, since I actually need it to get my H2C fully up and running.  As soon as that happens, this will be test printed and hopefully posted if there are no issues.  In the mean time, I have one other thought which I may look at, after discussing some feedback on the current case designs, though I'm not sure if it will make the cut or not.
2/8/2026: The P2S case modules are moving along, thanks to the help of an awesome community member who is assisting to test them.  I thought that the P2S spares were similar to the H2 and X1/P1 spares, but they are just different enough that the parts each had to be modeled to get the holders right.  I feel the P2S holders are over 90% there now, and the feedback has also moved me to make some changes to the existing H2 hotend holders, which will be updated in the upcoming version.  The pics show some of the test versions for the update, and a CAD rendering of the latest design.

2/12/2026:  I feel like the design is done, thanks to some great help and suggestions from a couple folks in the community who assisted me in testing the prototype holders for the P2S and H2 printers.  I also tested them with my spare H2C hotends (the left and right side ones), and I feel that the labels and holders are improved thanks to the feedback.  For the past couple days I've been building the profiles for the parts, and have settled on making one main (common) profile, and a separate profile for each printer (P2S, H2D/S/C).  That is 5 profiles in total.

I have some very generous offers to help check or test some of the finalized parts in the profiles, and will be sending some of the the profiles out to a couple folks for their thoughts, when they are ready.  I also plan to print all the parts for an H2C case, and am currently drying my filament to get ready for that.  The pics below show the "common" profile, which is completed, and some of the prototype parts used for testing. The 1st pic of the profile contains only the parts to build the case, without the printer specific modules.  It is quite a large profile, but really, only 7 plates are necessary, since there are 5 options for the case designs (with 2 types of lids for each).
