I'd love to see an easy guide to doing this with the Framework Desktop form factor. I didn't buy any of the silly little squares for the front of mine since I figured I could 3D print some later, but six months in still haven't gotten around to it.
The other idea I keep noodling about is creating modular gears and perhaps using a servo for a really cool dial indicator instead, but alas, it hasn't made it further than my ideas bin.
