These are the files for the 3d printed parts for the hydroponics tower for those that have a 3d printer and want to make their own. Zip format, simply extract them. Modified net cup holder (for pre made 38.5mm net cups). Net cups (scale down to 97% for good fit). I print these with pla+ at 0.2mm , 2 line wall, 20% infill, scale down the net cups to 97% for a perfect fit.
