Parametric design of a bottle holder to be used with small carabiner to carry standard PET bottles. Excellent for 0.5 and 1l bottles. 1.5l is a bit too heavy for it. I tried to make OpenSCAD code as parametric as possible so most of the dimensions can be customized. Any contributions are welcome.

Credits: Original idea came from a photo a friend found on pinterest, but I couldn't find original design to credit :( OpenScad code for Arc is taken from: https://openhome.cc/eGossip/OpenSCAD/SectorArc.html
