Star knob with hex nut pocket M8 - clamping knob, 3 sizes 36/44/54 mm, no supports

Five soft lobes. The shape you reach for when a knob has to be turned hard but must not cut into the hand. Takes a DIN 934 hex nut M8 from the back - the thread is steel, not printed plastic, so it survives being done up hard. The bolt runs right through, so its length does not matter. M8 is the machine-table size: clamps, stops, anything that must not shift under a cut. ## Sizes in the download All 3 diameters, same shaft fitting: | Diameter | Height | Volume | Weight in PETG | |---|---|---|--…
