Disclaimer: I ended up not printing it because I found a different solution to what I had planned. I attached the Fusion file with all the parameters so you can edit it to your needs.
I am certain the dimensions are correct. I would be worried about the stability using the same thickness bottom as the metal plate. I was considering adding some bracing of 1mm height on the inside. If you do so, do not go higher than 1mm. The plate is very close to the PCB components.
I definitely recommend PETG for this. The Stomp produces quite a bit of heat!
Feedback is appreciated.
