Glasses holder - Brillenhalter

thingiverse

You're out on the trails, and the changing light intensity is making it tough to know where to put your sunglasses. Putting them backwards on your helmet may look cool, but it's not a solution for trail riding on rough ground. A better option is the glasses holder - just stick one ear piece through the holder mounted to the handlebar and ride on. You won't have to worry about losing your glasses anymore. The holder needs to be printed with elastic filament (TPE) and 100% fill. Attach it to the handlebar using zip ties. It comes in two sizes, with the larger one being a scaled-up version (by factor 1.25) of the smaller one. Other sizes can easily be derived - even if there's a small error due to changing the handlebar diameter, it's not relevant.
