GoPro Plate to Handlebar

thingiverse

GoPro Clip Plate and 2 versions of a handlebar mount for said, one thinner where clearance is an issue. Single screw allows plate to rotate on the mount. There are light serrations between the 2 to allow for positive stops. I use them to mount flashlights, eg: https://www.thingiverse.com/thing:4780760 But, you could use the mount for, say, a GoPro if it's not dark :) The mount should be printed on its side for strength. PETG was springy enough to slip over the bars without issue. PLA might need a bit of heat to flex things. Skinny version is for clearance on crowded bars or smaller bikes. The plate is designed to print flat, no support, though it might take a quick scrape to clean up the overhang. Again, 2 versions. The skinny one is probably the one you want. The full version is for whatever, including holes for zip ties or screws as needed.
