This was my first real dive into Arduino and multiple button mapping. It took a significant amount of trouble shooting and learning the software to get things to map to the computer action.

Prototype 1:Started this project before I had a laser cutter and had tried to just drill through acrylic. It didn't work well, but it held my buttons during testing
Prototype 2
Still no laser cutter but I cut out using plywood worked much better for manually cutting out the holes
Prototype 3
Much better
Definitely post it!
I designed this from scratch but it's very simple
use this website to help make boxes. https://en.makercase.com/#/
You just put in the dimensions you want and it spits out the cut file. Once you have that you can just add your button placements in whatever software you use.
Thanks ! Do you have to precisely take into account the width of the laser ? Or do the tolerances allow some < 1 mm errors ?
I have never needed to adjust for laser kerf with that site. Put in the thickness of the material and it does the rest.
