Waterbottle-holder-Clamps for Bicycles (28mm)

My Bike had no options to mount the BANANABOTCAGE™ (https://www.thingiverse.com/thing:678170), so here are the clamps.
They are inspired by https://www.thingiverse.com/thing:2862824 (thank you, jroody), but i dont like the scews at the bottom.

Diameter = 28mm;
Screws needed:
- 2x M3x20
- 1x M4 (depends on your bottleholder)
