KBD67 MkII HHKB-Type Mechanical Keyboard Case

thingiverse

This is a 3D-printable case for the KBD67 MKII PCB, with a split backspace and a blocker placed atop the left control key. I created this to give myself a keyboard similar to the HHKB but with arrow keys (because I can). Do note, this is only compatible with the soldered version of the PCB. There are 4 "layers" to the design: the top, plate, bottom, and ramp. The plate holds the Cherry-MX compatible switches, and once the switches are soldered in, holds the electrical assembly to the rest of the case. The top and bottom layers make up the core structure of the case, which hold the plate using gaskets. Finally, the ramps slope the case and give additional structural rigidity. The case is chopped in a 2-3-2 configuration. In this case, the top part and ramp is comprised of two components, while the bottom case is made of three parts. This was done to avoid misalignment issues, and mitigates the issues associated with chopping up these parts (ideally these wouldn't be cut into sub-parts). The following additional components are required for mechanical assembly: - 16 M3x16mm socket cap screws - 8 M3x8mm socket cap screws - 1/8inch thick neoprene foam for the gaskets - 1/4inch thick neoprene foam for dampening (optional) The following additional components are required for the functional sub-assembly: - 1 KBD67 MkII PCB - 67 Cherry-MX compatible switches - 2 2U Screw-In Stabilizers - 1 6.25U Screw-In Stabilizer - A Compatible Keycap set
