RAM Mounts 1/4"-20 Female Thread Ball Adapter with Hex Post, B Size 1" Ball, Camera & Accessory Mount Adapter RAM-B-337U

I've got a RAM mount I printed in ASA that's been fine in a car interior for a few years now! Although in my case I used a purchased RAM ball, the custom piece I designed has a bolt through it into the purchased ball. You could do something similar if you end up having any issues with just the ball part, although I think you'll probably be fine!
