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
I have never needed to adjust for laser kerf with that site. Put in the thickness of the material and it does the rest.
