Over the door towel rack

This is a towel rack you hook over a cabinet door, I designed it for out doors which were 20mm thick.  You need to print 2 hooks and 2 clips.  Designed to be printed flat, no supports needed, just place a flat surface on build plate.  Fair warning, the tolerances are fairly tight.  I recommend that PETG or ABS be used, especially for the clips as PLA prints might be too brittle and just snap.  The assembly procedure should be self evident.
