Watering spout for 2 liter bottle

Featured in Make Magazine's Winter 2013 Ultimate Guide to 3D printing!

> (March, 2019) This watering spout was originally designed and built on a Makerbot cupcake 3D printer. As such, the tolerances are loose and probably won't work for you if you use a modern 3D printer with its improved accuracy. I encourage you to take a look at the list of derivatives to find one that may better work for your printer. Thanks!

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.
