I added a led bars mounting system to the well-known hydroponic tower project. I also updated the lid model for a 27cm diameter planter, which can be printed in one piece on a large H2 series printer. The wires to the lights are connected under the top cover using dual Wago connectors. My lamps are 1 meter long and have pass-through connections on both ends. This allows all the wires to be hidden and the entire structure to be easily removed for tower maintenance. You can attach any light fixtures using zip ties. If you have a printer smaller than the H2 series, just cut the long parts into 2 pieces and glue them together after printing. I also added files with mounts for 4 lamps.

I hope this was helpful!
