So I wanted to have a good case for my Jackpot Controller, but was not in love with the options. This is my first time designing something and utilizing it. It was designed to use a 3mm acrylic sheet (~75mm x ~136mm) depending on your tolerances.
I used tree supports and they seemed to work great.
I am also uploading the .step file if anyone wanted to tinker with it, as I'm sure there are more talented people who can perfect this model.
BOM:
Again, this is my first attempt at doing something like this and I would probably change a couple of things, but this suits my needs as-is. Hopefully this helps someone else!
