Designend from scratch, finally my first thing with some useful functionality. After some try&error it finally works pretty smooth.

Sliced with Cura 4.13, Printed on Artillery Sidewinder X2 (bed 70°C, nozzle 210°C). I do recommend to use a better resolution (0.1...0.15) since my 0.2 resolution was a bit too rough.

If you encounter to have a sticking lid, don't force it! Use some fine sandpaper (or an abrasive of your choice) you smooth the surface of the thread (do so on the lid and bottom part). This will improve the "smooth operation" a lot.

Let it cool down on the bed to avoid any deformation

Print was water tight, thread was able to hold water for some tie (only a drop now and then found it's way out) so stuff inside should be protected from rain or so pretty well.

UPDATE to v1.1: Tuned export settings, so "round" remains round and not "polygonal"...
