Needed a knob replacement for my moms old hand crank berry macerator that she uses to make jam. The old knob was made of wood and survived many many years of use but finally gave up and crumbled to pieces when she took it out this past year. Luckily with only a few minutes of modelling and printing we had a replacement made and she was back to making jam in no time.

Fusion360 file included in case anyone needs a similar knob design. Fairly quick and simple to modify.
