A pot lid grip that has an opening for threading an M5 screw through. I used PLA+ at a layer height of 0.2mm with an infill of 60%, but the higher the infill the better.

The M5 screws I had laying around where 21mm in length, which is reflected in the design. Just add a nut at the other end and make sure you are using non-rusting nuts and screws for safe cooking! I use this lid with low cooking heats and the glass isolates the heat pretty well so after a long amount of use time, the print did not malfunction at all.
