Summary

This is a very very simple design, to support small diameter (7 cm) plants.

The main idea comes from this excellent sophisticated design from HardyP :

Besides, there are tons of available designs on the subject :

The purpose of my design :

• quick to print (i haven't connected the ring and the rods : this is so much faster to print !)
• modularity
• clipsable (no glue)
• convenient (if the plant is already large and messed up, i opened on ring to make it easier to install)
• no support

The rods are 3.6 mm, the opposite female connector are 4 mm.
