Projector Slides

I just realized i could 3d print slides for my 35mm projector.

The slides are meant to carry pieces of laser printed transparencies, but obviously can be used for whatever. I found I had to use an 80 slide tray instead of a 140 slide tray to get them to work with it.

I tried to make a super thin slide at 1mm thick, which results in one layer on either side of the slot, but that still jammed in my projector's 140 slide tray. All slides worked fine in my 80 slide trays.

I also have a thrown-together calibration-ish type of slide that can just be 3d printed as-is, which I use to align my two projectors.

Use a light color so that it doesn't absorb too much heat from the projector's bulb.
