Customizable bike bottle holder

Simple bottle holder for bicycles. It's not higher than the bottle so it does not collide with a triangular bag above. You can shift the bottle location so you can lower center of gravity or fit longer bottles. If the sides are tall enough you don't need supports but for thin walls they are recommended. Otherwise, it flexes during printing.

Set the bottle diameter a little below the actual diameter to provide proper grip. If the grip is too strong, use a hairdryer and bend the fingers a little.

Print in PETG for flexibility. PC can work as well. Use more bottom perimeters to avoid breaking of the foot.

Model bottle holder 73, 140.stl is generic for bottle of diameter 73 (and around) with a narrowing at 140 mm (length).
