Windshield Wiper Bolt Cap

For some reason I find these caps just don't stay on my car. I'm not sure why, but my solution is to print my own as I need them.

You'll need to finish them to make them look nice. Recommend using the UV/Epoxy/cornstarch method if you need to. Alternatively, a quick wed sand goes a long way.

PETG for printing given the sun exposure.
