Stacking system for PET bottles

Easily printable modular system allows you to stack PET bottles.
Currently I have versions is for 1,5l bottles (9cm diameter) and 2l bottles (10,5cm diameter). If you want bigger, just ask me and I'll redesign it and upload more models.

You print each part separately and then attach them together. You can choose between M3 screws or printed connectors. The long conectors allow you to create a layer holder which can be easily taken with one hand and stored away when not used. You can even print a hook to store it above the stack.
See my configuration in photos.

The numbers are up to you. I use it with 4 bottles per layer and up to 6 layers without any issues.
