Coat hooks for kids with adjustable pattern (screwable interchangeable hooks)

Here is a design for swappable coat hooks to mount on a wall, furniture or any suitable support.

I wanted to be able to swap colors and shapes of the front patterns depending of the kids mood without having to drill again and again and again. Basically, you can print the mount system (001-fixation.stl) and screw it on your support (1 single hole to drill) then swap any of the hook pattern you wish.
The two-part design also allows to print without any raft, brim or support: no waste of time or plastic!

Personally, I preferred to print the mount cylinder in white PLA and the hooks in wooden PLA (will add pictures later). Only the pattern will appear in wood, since the thread will be hidden inside the white mount.

Feel free to rescale the objects to suit your needs, with the same relative height for both mount and hook to keep compatible a thread.
