This customizable star knob has curves in all the right places. I should know because I spent a lot of time calculating them. The number of points on the star and all other dimensions(listed in "Customizer Notes" section) are fully customizable allowing for a wide variety of shapes and configurations.
Knob may have a either a hex cap bolt, hex nut, or round shaft press fit into it. For round shaft (no bolt head or nut) set either boltHeadThickness or boltHeadDiameter to zero.
The Thingiverse customizer has an issue where some parts of the knob preview as transparent, but if you click "Create Thing", the resulting model should not have any such holes in it. Changing the angle can help if the transparencies make visualizing difficult.
Example STL fits M8 hex head bolt.
Enjoy and please post any makes you do.
