Bicycle Pump Seatpost Mount

Update: I've added a double bolt version, which secures the bicycle pump with a bolt, similar to the way you mount this holder to the seatpost. This design is 100% secure.

This compact and easy to print bicycle pump holder can be mounted to your seatpost (or any other round tube on your bike). The bicycle pump can be pushed in, whereas the front section
of the holder wraps around the seatpost. It can then be secured with an M3 bolt and nut.

Designed for a mini bicycle pump from AliExpress (link below), which is cheap and works great on Presta valves.

I printed this design in PLA and the front part of the holder is flexible enough to wrap around my seatpost. It's been designed in such a way that the thickness is exactly three perimeters (1.35mm wide with a 0.4mm nozzle). I'm not sure yet how long the PLA will last once it will be exposed to the elements, so if you can, I would suggest printing it in a more weatherproof material (such as ASA).
