Summary

I wanted a way to support a coir pole in the center of a pot, so it wouldn't lean if the climbing plant got too large.
Because I designed this for a specific pot of mine, this is less suitable for a print, and more to give you the idea how you can model your own for whatever sized pot you have.
The 2 parts bolt together firmly over the coir pole, while the support itself was super glued to the bottom of the pot rim.
The short cylinder is for the pole to sit on, but still allow drainage out the single hole in the pot.
