I couldn't find any GoPro quick release mount for Camrock TH70 so I designed this using upper part from GoPro Tripod mount by tmorris9 (https://www.thingiverse.com/thing:81333)
The base at the bottom is 39.6 mm exactly.
Tips:
Happy printing and videomaking!
Check my other videos at youtube.com/medyk3d and tell me if it was worth buying GoPro 9.
