Handwheel with heat-set insert M4 - clamping knob, 4 sizes 25/30/36/44 mm, no supports

A spoked handwheel. Uses about a third less material than a solid knob of the same diameter and gives the feel of a valve wheel. Bored 5.6 mm for a standard brass heat-set insert M4. Melt it in with a soldering iron at about 220 C and let it cool under light pressure. The knob then takes a machine screw as often as you like - that is the difference to a printed thread, which is good for a few dozen turns. ## Sizes in the download All 4 diameters, same shaft fitting: | Diameter | Height | Volume…
