Hydroponics tower with integrated net pot rings

In my tower, these rings leak around where they interface with the holes in the module (I'm assuming from capillary action) so I integrated them into the module. For use with these net pots . I've only printed the 3 port, but I assume the 4 port will print fine. I printed in PETG. 0.2mm 4 rings 30-40% infill no supports (there are unsupported “in air” but no functional or printing problems) brim if you want/need it
