$1,11CULTS PU - Private Use

Fine longitudinal knurling and a slightly domed top. The everyday knob: enough grip for a fingertip, quiet enough for a front panel. Fits a standard 1/4 inch hex bit shank (ISO 1173, 6.35 mm across flats) and turns the knob into a thumb driver for fine screws. The bore is built to 6.45 mm; printed holes come out a tenth or two tight, so the bit sits snug without a hammer. ## Sizes in the download All 4 diameters, same shaft fitting: | Diameter | Height | Volume | Weight in PETG | |---|---|---|-…
