Modular self-watering pot

Remember to add supports under the connecting tubes. The new brush tool in the Prusa Slicer works great for this. The supports are easy to remove and are only needed at this point.

The connections should not leak, but if they do, use glue or silicone on the tubing.

If you would like to use a pump for hydroponic growing, the final pots come with an internal connector for it (wc - with connector). The water then flows through the upper holes and from the last pot returns to the first pot through the lower tunnel.

I've added different pot sizes so you can choose what suits you. Mine are two of 100mm height and 150mm diameter and one respectively 150mm by 200mm  

Everything was printed from Prusament PETG Navy Blue and clear with a default profile height of 0.2mm with only forced supports. Connector had brim turned on.
