Glasses holder - Brillenhalter
grabcad
Riding trails with changing light intensity and wondering where to stash your sunglasses? Wearing them backwards on your helmet might look rad, but it's no solution for rough terrain trailriding. A better fix is the glasses holder - simply stick one earpiece through the holder mounted to the handlebar and ride off into the sunset without worrying about losing your shades. The holder needs to be printed with elastic filament (TPE) at 100% fill. Secure it to the handlebar with zip ties. It comes in two sizes, the larger one being a scaled-up version of the small one by a factor of 1.25 - other sizes can easily be derived if needed (the minor error from adjusting the handlebar diameter is negligible).
