Toothbrush head shelf clip (5mm shelf)

I made a shelf for my bathroom using some 3D printed brackets and 5mm acrylic.  These clips are designed to fit onto the edge of the shelf and each clip hold one brush head.

Print right side up with supports.  I tried printing it with the prongs down towards the bed but the contact area was too small and it came loose.

If you want to fit a different thickness of shelf you should be able to scale the model vertically, keeping X and Y at 100%, or edit the freecad source file.
