I bought a bunch of 4oz dropper bottles and needed a way to store them for use. There were some models, but none of them were exactly what I wanted. I decided to use bestagons because why not.
I made single, double, and quad so you can mix and match and build your own. They use dovetails to connect.
I also included end caps if you want to square off the ends.
The hole is 49mm/1.9in wide for 4oz bottles.
The author marked this model as their own original creation.
