Parametric knobs for hex bolt, fusion 360 included

A parametric model that allows you to generate round knobs that embed hexagonal bolts or nuts is provided for your convenience. You can easily change the size of the knob and the embedded bolt/nut size using the Fx features of Fusion 360. I made this model because I need a large range of small to large knobs that fit specific tools. And I guess te model might be useful for other people too even though there are quite some knob models around. Apart from the parametric model I have also included a range of possible knob sizes that fit different metric bolt sizes (M2-10). The model itself is not really fixed to metric sizes so it can be adapted to imperial sizes. It prints well with a basic 0.20mm layer profile that should work just fine. For the smaller knob sizes .16mm or .12 mm layers could be better fit. Support is not really required but does give a better flat profile for the bolt/nut head. Can be printed with PLA but I prefer PETG-CF for strength, ASA/ABS would do fine too. Increas
