Half-toroid cabinet knob

Replacement doorknob for the cabinets at my parents' house. Here's the source [OnShape model](https://cad.onshape.com/documents/4b688c0688506ab048db78bc/w/b7292ab51597c7835b64478e/e/1a1766c921a0a853e9ef8440).

For use in a new installation, the model should ideally be changed to include printed holes for screws. This wasn't an option for the existing install, since the original parts didn't have drilled holes, and each knob was drilled for its door.

These were printed with breakaway support, and then I sanded them to get an even finish and sprayed with clear matte acrylic.
