star knob for 1/4-20 bolt

thingiverse

designed to press-fit a 1/4-20 bolt into. Works great for projects that need a knob. Should be able to print with supports in either direction without issues, but it's easier to remove them if you have the bottom cylinder of the star knob on the bed and print supports for the rest. Supports done the other way uses less plastic, but harder to remove from the part.
