Simple easy print storage boxes, print great on 0.4mm nozzles. Made in openscad and fully customizable(comments in code). Use recycled pop bottle lids to reduce waste(a printable lid is included in case needed).
This have a very good seal and I am using them to store very small beads and similar without any issues.
