20mm (2cm) hook retainer (+4mm)

thingiverse

I have been looking around to find a small hook/lock that would simply press down a container of mine but didn't find anything so i quickly designed this part. Diameters: 15mm x 15mm (inside) 24mm x 24mm (outside, with the retaining part(4mm)) If you scale it at 134% you will get 20(.1)mm x 20(.1)mm on the inside and 32.16mm outside Rounded edges (outside) so you don't hurt your fingers! (that's why i rounded them) Print them at 100% Infill if you wish, that way they will be really sturdy, i did them at 20% (Cubic) and it worked out just fine Print time for me is 12 minutes at 50mm/s speed per clip. You can probably do it a little bit better here and there, but i did this for myself and i don't care about fine tuning it for now. **Edit 28.05.2023 - 21:00** I have added a "more_round" version, you can see it in the pictures.
