Replacement handle for a generic edge-safe can opener I've had forever. The original handle was designed just to press fit over the top of a nut and lock collar - this does the same.

This was actually one of the first models I did, which is why there are two versions. My initial design was perhaps overly chunky. But it also proved to be much stronger than I ever expected, and has been working without issue for two years. So I've never had a reason to print the refined, more space conscious version I modeled later which not only uses a fraction of the plastic, but should also be a bit more comfortable to use if you have normal sized hands.

Printed with a .4mm nozzle, .3mm layers, and 30% infill.
