The model is still in progress; any suggestions are welcome :)

The main concepts behind that support were:

• make them easy to print
• stackable
• easy to mount
• can be printed using PLA

TODO:

• More sizes should be available.
• Rods can damage the roots during mounting.

Update (16-05-24):

I added a circular medium version, which is less harmful for plants and easier to assemble. Reworked rod sockets.
