3x4 net cup for 4” pvc duct

thingiverse

This net cup stands out from others on Thingiverse as it's tailored for a rain gutter grow system, which you can explore further on YouTube. While there are more suitable options available for hydroponics, this design has its own unique features. Its distinguishing characteristics include a 3” diameter lip that prevents the cup from passing through a 3” hole in the bottom of a bucket or planter. The mesh openings are small enough to keep dirt contained within. Additionally, the net cup is extra deep at 4”, allowing for a lower water level and reduced weight in the 4” pipe. With a decent printer and an infill percentage of 40%, this design can be printed without the need for rafts or supports. The walls are 0.1” thick, providing excellent sturdiness and structural integrity – I've personally tested it by standing on top without causing any damage.
