Skirted knob for D-shaft 6.0 mm - 4 sizes 16/20/25/30 mm, no supports

A slim head on a wide knurled skirt. The skirt runs past the panel as a scale ring and gives the fingers something to hold that the head alone does not. Fits a 6 mm shaft with the flat at 4.5 mm. The bore is built to 4.6 mm, the knob-side figure from the OKW catalogue per DIN 41591 - the extra tenth is the standard's own clearance, not slop I added. ## Sizes in the download All 4 diameters, same shaft fitting: | Diameter | Height | Volume | Weight in PETG | |---|---|---|---| | 16 mm | 17.6 mm |…
