Optional: I used 3, 3mm heat inserts and 3, 35mm bolts. It should friction fit together really well. Up to you. I was worried about taking it apart a few times to change things it would loosen up. So far after numerous disassembles it sill fits great. As of now, they are only there for aesthetics and are not needed. If you plan on using the heat inserts, remember to increase the number of perimeters. I plan on adding a Teensy dev board later so there is a ton of room in the body for whatever.
