I was sick of buying bottles around during my bike rides because I didn't have the time (or the will…) to go to a store and purchase a bottle holder, so there it is!
You can find the dimensions in the pdf, it fits perfectly on my bike (Rockrider ST-900).
The print doesn't need supports (I hate them). I printed it in PLA, but a more resistent material would be bettere, even a < 90 shore flex one (if you have the patience and the time).
Enjoy!
