It's a small pick stand which turns your guitar-pick into a Telecaster body. It should fit all picks up to 2mm thickness.
You can print it as it is and won't need support. It's a good idea to place the seems in line or even use the seem-paint tool to prevent ugly seems at the front – in my experience the “rear” option in the PrusaSlicer works best. I've used a layer-height of 0.15mm to make the “details” more visible.
At last use some professional, double-sided, problem-solver tape to attach it permanently to your amp.
Notice: I once saw this design (with an ugly neck) but can't remember where, so I decided to make my own as a gift for a friend.
