Grow Light Mounting System for Modular Hydroponic Tower

I had trouble getting the original design to hold together so I created a more complete mounting frame for my lights. This is based around the 4 ft long grow lights here: https://www.amazon.com/dp/B099PPYRPQ I cannot guarantee nor would I expect it to fit any other lights without additional modification.

This assembly uses laser cut parts for the outer rings since they are too large to print in one piece. The ring profile is provided as a DXF file. I recommend cutting two sets and gluing them together for extra strength.
