Reversible Table Hook Ledge Hanger Gadget Thing!

There are plenty of similar models around, but I made this specifically to hang christmas stockings. I wanted a hanger that was:
– Reversible and stable in each configuration
- Laden with extra facets and grooves for hanging or securing bits and pieces
- Nice and grippy
- Sized well for anything up to a 35mm*35mm overhanging ledge, with some extra wiggle room.
- Tolerant of reasonably high weight (this model has been tested with 15kg)
- Slim and conservative of filament

- Visually interesting

So here it is. Just pop it onto the edge of a surface and hang your thing! 
If you need additional holding strength, resize the Z-axis in the slicer up to make it broader. Consider using PLA-CF for strength, although I printed in PLA Matte (not a strong material) and it works very well.
If you need to hang on a larger/smaller surface, resize the Y-axis in the slicer.
