GoPro Ball Joint Mount Adapter by RobertCL

A standard GoPro connector with a 15mm diameter ball on the end of the stick to convert an old GPS windscreen mount into a GoPro mount. Print on it's side as shown in the picture for strength. I used Craftware to slice and generate some support under the cylinder, though if your printer bridges well you can probably get away with no support.
