Potentiometer Knob 06

I never seem to have the right potentiometer knob for the job on-hand. I could keep a reserve of interesting knobs on hand, but that takes space. Instead, I custom design the knobs, as needed. Here is another of my 3D knob print designs with a squarish shape. The knob is designed to fit a 6mm potentiometer shaft. The knob has a 12mm base and has a height of 14mm, not including the indicator marking.

The knob is held in-place by an M3 threaded brass insert, 4mm long. Carefully fit the brass insert with a heat source such as a soldering iron.

To make the print result more interesting, I do a filament colour swap near the end so that the raised text is printed in another colour and make it more visible. The filament colour swap is setup in your slicer software. Setting up the filament colour is easy in PrusaSlicer, other slicers probably, too.

My print is made in PETG 1.75mm Aurarum black and white filaments, with 0.05mm layer height and 15% infill on a PRUSA I3 MK3S printe
