ErgoDonk Zero case

Cases for the ErgoDonk Zero keyboard.  

Tested with PCB v0.2.

Should only be used with MX switches. 

Right and Left hand cases are unique and not interchangeable. 

The keyplate is mirrored for the right and left hand. They are split into separate files with a LH/RH suffix to prevent any confusion. The should be printed with the notches up, and the side that shows through the keys is against the build plate. They are oriented that way in the .stl & gcode files.

You can add print helper objects to keep the edges from curling. There is a ‘sacrificial’ support below the bridge that connects the island in the middle of the thumb cluster. Snap that off by hand. (It's highlighted in the image with the yellow arrow).

Use 8mm screws if the backplate is used. If no back plate is used, go with 4mm screws.

UPDATE: April 2026, fusion 360 source files have been added. The were not initially intended for release, so they are a little rough around the edges. (i.e. no components, only bodies)

The case sketches started out as KiCad PCB exports, so the key profile shapes don't always line up 100%, so there's lots of 'sliver' overlapping shapes. This resulted in tons of manual corrections & shape tweaks both during the sketch and extrusion phases.

I lost the thickaronie keyplate source file, so I've created it as best i can.

You'll find the start of a case for a choc variant in there, but i could never get my hands on a full set of choc keycaps, so i never finished it.
