A heat inserted nut/knob on a c-clamp broke from my pasta machine, and because it didn't exist on makerworld i made a simple parametric model to generate a new c-clamp wingnut wich can be inserted by heating up the bolt with a soldering iron.

Sizing

For the correct size generate on makerworld.com so not from the app a new .3mf file.

0.2mm less than the male bolt.

Formula:

Measured bolt diameter - 0.2mm = Diameter size used to generate wingnut

This is a simple file i wouldn't go beyond 10 mm bolt sizes, but you can hit me up and i will make a better model
