I accidentallyed on to an etsy search for diy/3Dprinted input devices. I didn't know things had gotten so wacky. There is a charm in it.
individual images as pictured above, with links
I only included general-purpose devices to be used with a computer. There are also a lot of similar that are more particular in scope, like for gaming or music.

Anyone using, or tried using, any of these?
Many of these are not too wacky, just alternative keyboard layouts.
For alternative mice, tbh I think standard mice are pretty close to optimal. Any time I try another type of pointer input I find it harder to control, but maybe that comes with practice. I also haven't tried one of those stationary ball mice where the ball is on the side of the mouse but maybe that could be ok.
