This stand can be used to vertically store unstackable lids etc. I use it to store the lids of my mini casserole vessels.

The included scad file enables customization for various dimensions and lid counts.

The pre-rendered stl file features the following dimensions (which fit the round lids of these vessels: https://www.amazon.de/UNICASA-Auflaufförmchen-Auflaufform-Durchmesser-Geschirrspüler/dp/B09KTSH9FQ/):

• depth 80 mm
• height approx. 55 mm
• 4 lid slits, 18 mm wide, 36 mm apart

I printed the stand without supports in Prusament Clear PETG with 0.2 mm layer height without support on my MK3s+, which worked fine. PLA should also be no problem.
