Ikea loft bed hanging hooks

A set of hooks for hanging things underneath the Stuva Fritids loft bed from Ikea. Designed to snap into the rails snugly so that they won't fall out easily. Contains two different parts:

* End Clip.stl -- Print a few of these clips to put between the first slat and the end of the frame.
* Redesigned Clip.stl -- Print many of these to snap between the slats for hanging things.

I measured the bed as assembled, there's about 17mm between the first slat and the frame, and 67mm between the rest of the slats. The redesigned clip is slightly over-sized so that it should fit snugly between slats, accounting for tolerances during assembly.
