Hydroponics net pot seedling starter

I'm building https://www.printables.com/model/63055-upgraded-modular-hydroponics-tower-more-compact-st and I needed something to start my seedlings so I designed this really simple box to start seedlings.

To make transplanting easier, I designed it to use the same rings and net pots that I'll be using in the tower (so I can just transport the ring and net pot all at once.  The top has a small lip to fit into the base, but won't slide into the base, so you can pick it up to check on the root growth or to add more water/nutrients as needed.

• 30% infill
• no supports
• no brim
