This is a quick snap clamp for your mobile phone. The phone snaps in place with one move.

To connect the moving parts together use small pieces of filament. The base slides into the mounting part and locks with a piece of filament through the small hole. You will also need an M5 allen bolt and a nut to mount it on your handlebar. There are two versions depending on the phone width, and three different mounting options (two for handlebar and one for stem).

Although the clamp snaps firmly, it is advised to use small rubber bands or pieces from tubes (28mm road tubes) at the point where the arms touches phone, to ensure it doesn't slip at all.
