Watering spout for 2 liter bottle
by edmo, published
This is a watering spout for a 2L bottle or anything that can screw on to soda bottle threads. There is also a Autodesk Inventor file attached that has no threads, so you can adjust as you see fit.
The point here is that, thanks to the wonders of 3D printing, you can repurpose what would be a piece of trash into something useful. This spout would be useful for seedlings or other small plants that require measured amounts of water. Also, this watering spout has 1/8" thick walls. You can't buy something this durable at the store!
I've recently (May 2013) uploaded a modified design file that takes care of some sealing issues and adds threads to the bottle. I added the threads in with an assembly, so the STL file got a lot bigger in the process. It prints great, though. If it still leaks, try taking the rubber gasket out of the 2 L cap, drilling it out and using it as a washer.
ljudmila changed up the threads:
Chickan put this on a watering hose:
chickan also made one with different threads:
uumeran adapted it to a milk jug:
CaptKirk made it smaller and more efficient:
steveweber314 turned it into a low-pressure garden hose nozzle:
Don't have a 3D printer but want one? Message me and we can work something out. :)

I'd recommend running this through the dishwasher before you water your plants with it.
