Blinds Rod Spinner

All the rods to rotate my blinds had broken and I wanted a solution that would keep kids hands from messing with the blinds. So here it is, a super short blinds spinner. This is for one sort of blinds at the moment, might upload more soon.
I printed this at 100% and it was kind of a tight fit, so I reprinted it at 102% and it is much easier to slide onto the hook and stay in place as a friction fit.
