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.

I am using Elite Pi microcontrollers (RP2040)

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

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

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.

Thanks. Yep, cable is DIY
