Hexagon knob for D-shaft 6.35 mm, shallow flat - 4 sizes 16/20/25/30 mm, no supports

Six flats instead of eight. Reads as a tool size and looks right next to anything held by hex screws. For the 1/4 inch shaft with the shallow flat, 5.5 mm remaining. The other 1/4 inch shape leaves 3.96 mm - measure across the flat before you print. ## Sizes in the download All 4 diameters, same shaft fitting: | Diameter | Height | Volume | Weight in PETG | |---|---|---|---| | 16 mm | 17.6 mm | 2.1 cm³ | 2.6 g | | 20 mm | 17.6 mm | 2.9 cm³ | 3.7 g | | 25 mm | 17.6 mm | 4.5 cm³ | 5.7 g | | 30 mm…
