I accidently broke the swivel base on a V3 pro while changing SD cards. Doesnt seem like I could find any replacements and even asked customer support.
Decided to CAD up a replacement and 3d printed. works pretty decent. not as 100% as well as the original but 100x better than the broken one. Hope this helps someone.
