This is a 3D-printable high profile case for the Alpha keyboard by PyroL.

The bottom panel can be 3D-printed or lasercut from acrylic or whatever material suits you.

Fusion 360 project is included, and case height is parametrically adjustable from project parameters.

The newest changes to case height has not been test-printed, but comparing that to the previous one which was a bit too short, I think this works really well.
