I've gotten around to printing the case and plate and here's the first prototype!

I have yet to actually add electronics and test if everything will fit.

There's also one slight problem, I had to make the plate 2mm thick since 1mm was much too flimsy, but the key switches don't clip in well to the 2mm thick plate. I'll be reprinting a slight redesign that has insets on the back for the keys to snap into, but is thicker elsewhere to add support.
