This system is the Double Tower companion of the Single Tower system available here: Modular Single Tower Hydroponics System by 3DMason | Download free STL model | Printables.com

Please note that the lid pieces are unique to the Double Tower system and are not necessarily compatible with the Single Tower version if used together. Double Tower versions of planting modules are spatially altered to minimize crowding of plants, but Single Tower planting modules can be used in tandem with these versions, if desired.

The modular hydroponics system consists of three main parts:

1. The nutrient solution bin;
2. the 3D printed lid;
3. the 3D printed tower(s). 

The system is designed to be configurable in either a Single or Double Tower design to maximize its utility for a variety of end users (researchers, educators, etc.) while remaining relatively inexpensive to manufacture. Users can easily mix and match components for their application or integrate components into other growing systems. This hydroponics system was designed to work with Uline S-20588GR 20L Round Trip Totes (ULine; Pleasant Prairie, Wisconsin, United States).

Individual parts (e.g. plant pots) can be adapted and used for other hydroponics systems outside of this tower system. We recommend printing in PLA at 20% infill, but other materials such as PETG could be used instead.
