Bicycle bottle holder

A heavy duty water-bottle holder, mainly created for my needs: ruff terain or tricks involving hard landings. Now, i created this design to fit my water-bottle like a glove but if you're bottle is a bit smaller you can put a strip of foam in there but i do plan to modify and make this adjustable in the future, most of all GIVE ME FEEDBACK!!! I need to modify and update this and i will take all comments into consideration.

(ALL MESURMENT ARE IN PICS) note that is in millimeters!
