SummaryEDIT: Updated the design for 25mm bars i was tired of all the overly designed clunky gopro mounts for bikes so decided to make my own minimalist design that require no hardware and only uses 2 zipties. for best results, put a small strip of rubber tape or other grippy surface under the mount so when it is tied down it helps it stay in place without rotating forward or backward. you want to print this standing on its edge, not flat like it would normally sit. the yellow picture of it is the proper orientation for printing it to get the best results.
