Knob M5

I was building a tool arm and needed an M3 nut but re-adjustable. The local DIY store can't help so I build this one.
Others made M5 nut handles however this is customized and the nut integrated.
Integrating the nut is done by a trick: using Prusa Colour Print option to stop the print and lift the print header. Now you can easily place the nut into the model and continue the print. Take care you exactly stop right before the next layer would cover the nut and your head is not crashing into the metal.
The design is based on https://www.thingiverse.com/thing:641854 for the handle, the rest has been modified.
The ColourPrint feature can be used from Prusa website: https://blog.prusaprinters.org/color-print/ or even better now integrated in the latest PrusaSlicer
