Growbox Irrigation Dual-Funnel

Inspired by DBert's design and added another seperated chamber to water/dung two plants independently.

You can use M4-30mm (nuts outside, see my Pics) or M3-25mm screws (nuts in the slots).

Printing: Print it standing with the tubes on the buildplate. Just support where the tubes touch the funnel. 

I also designed a clip which lets you guide the tubing down to the plants bound to a 16mm pole:
