About this 3D model

Stop hanging your sunglasses on your collar, helmet, or stuffing them into a pocket where they get scratched or lost. This Backpack Glasses Keeper is a compact, 3D-printed hook designed to securely hold your sunglasses on the front chest straps of a backpack. It clips directly onto the frontal webbing straps that keep the backpack closed on your chest, keeping your glasses stable, accessible, and protected. The hook firmly locks the glasses in place, even during rough movements, fast riding, hiking, or trail running, without damaging the frame or lenses. The contact surfaces are smooth and rounded, so there are no sharp edges that could scratch or stress your eyewear. Designed to be universal, it works with most backpack chest straps and fits a wide range of sunglasses and sport glasses. It prints in just a few minutes, uses very little material, and adds virtually no weight. Already tested in real outdoor use, this clip stays exactly where it should, keeping your glasses safe when you’re not wearing them and instantly ready when you need them. Small part. Big convenience.
