The internals

Thanks! The top surface looks pretty clean because I used the ironing feature, where the hot nozzle of the printer runs across the surface without extruding filament (or very little) to even out imperfections and small gaps. The print has its problems tho, probably like any 3d print. Optimizing your 3d printer and the print results is basically a hobby in itself.

It feels pretty good and the sound is actually okay too. Maybe next time I'll try it with a PCB. One advantage of hand wiring is that the RGB also shows through the top. That wasn't really intentional, but it looks nice. A PCB would have blocked the light and I would need to add per key LEDs for the same effect.

Thanks! I can give you the files so you can print it yourself 😉

Thanks. Yep, cable is DIY

I was indeed thinking of this keyboard when I designed the case.

I have three different kinds of keyboards. Regular, Alice and split ergo with columnar stagger. It always takes a little while to get back to speed when I switch boards. But I think that the layouts are different enough so that a distinct muscle memory forms for each one. I guess that the most important thing is that you should be fairly proficient with touch typing on a regular board before trying a different layout. If you are still in the phase of learning, I imagine that it gets really frustrating.

Feker Alice 98 I'd say.

I am using Elite Pi microcontrollers (RP2040)

I definitely wanted stabilized space bars. I don't like 1U for space and 1.5 or even 1.75U unstabilized is not really great in my opinion. The space bars on this board are XDA blanks because 2U cherry profile bars are hard to come by if you don't want to spend a lot of money on the bars alone.
