Square Net Cup - 1.5 inch (36mm) grow cube

thingiverse

This is a hydroponics net cup that doesn't need clay pebbles or any other grow media to support the grow cube. The grow cube fits snugly into the net cup. This design leaves a large area of the underside of the grow cube exposed, preventing obstruction to root growth. It fits within a 3-inch hole and holds a 1.5-inch grow cube. I have other designs in development and intend on creating more if requested. Please comment on the size (hole and grow cube) that would be best for you, and I'll create the most popular one. I've used this design for growing various things with no problems, including Chillis (in pictures), Giant Basil, Coriander, and Various lettuces. It's been found to work best when printed without supports, as removing them usually results in damaging the net cup.
