Co2 cartridge holder for Bike seatpost

thingiverse

I really liked the idea of Ktronik, but I needed to have some closure, so as not to lose the bottle on the route, so I made a quick closure and after several routes (with falls included) and that it does not fall, I can say that it works well and is comfortable to wear. The bottles enter tight by screwing, so they do not move. As a recommendation, for the grip of the clamps, put an old camera on the wheel so as not to scratch the seatpost. I hope you do well
