I used 3 mm Dibond which essentially is two layers of aluminum with a plastic layer in between. I chose it because it looks cool and provides stability while still being able to saw, cut, drill, and sand. I designed it in a drawing program and had it cut by a cutting service. It was charged by the number of cuts / openings to be made so it cost me 86€ but looks ery professional. I would use it again if I’d ever redo the project.
