Nalgene bottle holder for bicycles

The bottle cage and bike mounting bracket are printed separately. Use epoxy or some strong glue to glue them together. The bottle is secured in place using bungee cord. I used was 4-5mm bungee cord.
Add one flat head M4x8 screw as an attachment point for the bungee cord.
Using supports is recommended.

There are two versions available. One with strap attaching on side and one where the strap 
attaches at the front.
