<p>A ¾" schedule 40 PVC pipe-coupling that adds a 2 liter soda-bottle (standard US-threads). &nbsp;</p><p>I created this as a cheap way to add a fertilizer-chamber to my PVC drip-irrigation system. &nbsp;Thread-coupler is joined from this model: <a href="https://www.thingiverse.com/thing:13826">https://www.thingiverse.com/thing:13826</a></p><p>Print in either a strong plastic, or at full-infill since this will be under pressure. &nbsp;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.&nbsp;</p><p>Since this is all set to pretty specific tolerances, resizing is going to break things.&nbsp;</p>
