GoPro Hero handgrip with bike grip.

thingiverse

Designed this GoPro handgrip on which you can attach bicycle handgrip. Middle part is hollow which is gonna save on weight and material. It has generic GoPro mount on which you can screw any GoPro camera or accessory that has this mount style. Handle size is about 85mm to the rounded part and about 87mm to the end part. Diameter is 22mm. Measurements were taken from my own bike handgrip, but i assume that its a generic standard for all handlebars. Longer grips will probably be needed to cut shorter. Idea is that you can fit a spare handlebar that is used and taken from your own bike, or get yourself a new one, that fits your style. Very comfortable in hands, since most handlebars are designed to be that way. Screwholder is included. Print it standing, with Brim enabled, so it adheres to build plate well, without tipping over. Same with screwholder. 100% infill is recommended for better strength. I used 1mm nozzle on mine, but smaller sizes will do as fine. Result from a 0.4mm will probably look even better.
