Krtkus Retro Case

Check out the GitHub page for more context and the complete build instructions.

Case for the Krtkus keyboard, designed to accomodate a finished build of the Krtkus PCB. Pieces just lock each other in place. The PCB is then attached with 5 M2x6mm screws.

While the Krtkus PCB currently only exists in low-profile Choc V1 and KS-33 variants, original keycaps from retro keyboards can be used if you print a stem adapter. For example, my build uses the AT101W Alps keycaps with a custom built stem adapter.

The manufacturing file for the “base” model contains 100% infill density modifiers for the PCB support beams, this is because they're under a lot of stress when bending the PCB. You might be able to get away with less, however 100% seems to be the right amount to give PLA just enough strength not to bend.

Tested with PLA at 0.2mm.
