Projector Elevation Adjustment Disks

Portable computer projectors have an adjustable foot (screw) for elevation. They're always either not high enough, or broken, or both. This leads to a scramble to find some way of tilting up the projector. A stack of these disks does an excellent job. They're small, so they'll fit into the projector's carrying case, they interlock, so that the ones in the middle won't slip out, and the top one will have an indentation for the existing projector foot to fit into.

I've provided 3 different sizes, approximately 8mm thick, 4mm thick, and 2mm thick. Having 6 of the 8mm, 2 of the 4mm, and 2 of the 2mm makes for a good choice.

Caution: Do NOT use PLA for these. PLA gets soft at about 50C (122F), and some projectors get hotter than that, plus it's easy to reach those temperatures in a closed car in the summer (especially here in the Phoenix area).
