Ratcheting Clip for Towing Mirror

I created this model as I discovered that I lost one of the clips that holds my towing mirror to my truck.  Instead of going and purchasing a new mirror or tracking down replacement parts, I decided to print one out.

I printed this clip in PETG so it would hold up a little better.  I made mine completely solid so they were stronger but I would guess that the infill could be less.

The brand of mirror is CIPA.
