Customizable Knob with Hidden Mounting

I wanted coat hooks a bit like thing:52764, but the code wasn't to my liking, so I redid the programming. The code is fully customizable online to allow a very wide range of designs.

The mounting works with just one screw and hides the screw when mounted. The screw hole is nicely designed so it snap fits very tight (see instructions).

The STL's named "Knob_XX_XX.stl" are the ones I used to print my coat rack, the examples are just to show some of the different possible forms.
