Hello, i design and print this knobs for my kitchen hob since the original one lost some painting during this 12 years.

I print then in PETG, much stronger than PLA with water and chemical product for cleaning.

You will find tree version of the insert (inside part) since the metal stick were you'll fit it may be more or less loose.

Glue the two part together and print as for the STL files. For the know use support.

Enjoy
