Holder for 50ml centrifuge tubes

Summary

This design is a series of holders for 50ml centrifuge tubes.
The holders can hold 1,2,3,4 or 6 tubes.
It can print without supports but you should make sure to have a very good bed adhesion.
The shape is designed to allow to see the base of the tube unobstructed, useful when you use it for decantation.
