HHKB-7U Mechanical Keyboard Case

This is a 3D-printable case for creating a mechanical keyboard with an HHKB layout, with a split backspace and blockers. It is compatible with most 60% PCBs, but specifically I have assembled with with the XD60 and DZ60 soldered PCBs.

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 require
