3/4 inch PVC coupler with 2 liter soda fitting for irrigation

Uploaded V2 - better tolerances all around, and significantly shortened the overall length to cut down on plastic

A ¾" schedule 40 PVC pipe-coupling that adds a 2 liter soda-bottle (standard US-threads).  

I created this as a cheap way to add a fertilizer-chamber to my PVC drip-irrigation system. 

Print in either a strong plastic, or at full-infill since this will be under pressure.  You'll also likely want to add some rotating coupler to your system so you can screw in the 2 liter when its full of your preferred fertilizer. 

Since this is all set to pretty specific tolerances, resizing is going to break things.
