- needs some supports for the finger tab (or remove it and print separately to make it fit on a Prusa Mini)
- use a small wood screw to secure the parts one to another (it tends to work using just the "round fastening", but it's safer with a screw; after putting in screws, move the lid up and down a lot to make them easier to move)
- I stuck a couple of coins in the front of the lid, near the finger tab, so that it closes by itself
- glued some rubber feet on the bottom, so it doesn't move around
- it was tested with paper, sitting in bright day room light, then used in the darkroom for a couple of months; worked fine
- it was printed in black PLA with a 0.6mm nozzle and 0.4mm layer height, but anything should work
