Cricut Cartridge Body

My wife's old Cricut cartridges have become all sticky from the coating breaking down, and a couple of the cases were broken, so I offered to make some replacements so she can work with her machine without the issues that these problems bring.

The model is super basic. I made it thin to print quickly and just provide a shell for the internal circuit board. If you want something more robust you'll need to remis and add thickness to the exterior walls and potentially add some additional structural alignment bits - I spent WAY too much time on this as it is, and it is fine for my purposes.

You'll want to print both pieces with the flat side down (the models are oriented how the fit together). I printed with default settings @ 0.20mm layer height with the tail end of some silk PLA. Came out fine, and works. Reuses the screws from the original cartridge, so no additional hardware needed other than the cartridge you are replacing the shell on.

I also printed with supports on the build plate so the countersunk screw holes printed correctly. I used a small screwdriver bit to pop the supports out from the inside after printing. If you need to clean up the outside screw holes, I recommend just running the screws from the inside to the outside one time - that clears out any debris and pre-threads the hole for final assembly.

Lastly, I assume Cricut makes lots of different machines, but this model fits in the recess in my wife's when closed. That's the only resource I had for sizing other than the carts themselves, so YMMV if you have a different machine. REMIX away!
