Tow Ball Cover (Australian)

I tried several other tow ball covers and none were a good fit… too loose. I modelled this one to be “snug”, with the bottom of the cover flexing over the base of the tow ball mount and being a friction hold.  It is so snug as to not be able to pulled off by hand, so it’s unlikely to be stolen in a car park. I use a screwdriver to lever it off when I want to tow something.

I printed in PETG for the flex needed To lock onto the tow ball base.
