Six-spoke handwheel with heat-set insert M3 - clamping knob, 4 sizes 25/30/36/44 mm, no supports

Melt it in with a soldering iron at about 220 C and let it cool under light pressure. A printed M3 thread strips after a handful of turns; brass does not. ## Sizes in the download All 4 diameters, same shaft fitting: | Diameter | Height | Volume | Weight in PETG | |---|---|---|---| | 25 mm | 9.6 mm | 2.1 cm³ | 2.6 g | | 30 mm | 9.6…
