Summary

Here are two reducing adapters so that you may print the modular components at 75% and 50% scale and mate them to the original size tower.

I created the maximum Prusa MK3S sized reservoir that you should print in PETG. The cap for the reservoir has a slot for AC line pass-through and a small hole that allows you stick a cork on a skewer and have a level indicator.

I created a cone reservoir that I scaled down to 75% or 50% to start seeds.

I added a "rain catcher" module. This is for and indoor garden. I find that the tower occasionally leaks water down the sides. This module will catch the leak and route the water back into the reservoir.
