Watering spout for 2 liter bottle by edmo Jun 22, 2011

Featured Thing!

Description

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.

See chickan's version that adapts this to a garden hose here: thingiverse.com/thing:95723

chickan also made one with different threads:

uumeran adapted it to a milk jug:

Don't have a 3D printer but want one? Message me and we can work something out. :)

Like Dogecoins? So do I!

Probably. I can't help it. I was raised this way.

FYI: I think this model needs to be scaled up 25.4x for inch
&
gt; mm conversion.

Thanks! I think your idea of allowing it to shrink onto the bottle would work. However, I think I just didn't compensate for the width of the extrusion. At any rate, it does screw onto the bottle, even without the threads. It will probably strip out eventually, though. If you wanted to try the shrink fit option, I would print it at about 99.5%, then soak the top of the spout in boiling water to soften it up. Alternately, I may add ribs to the inside of the spout so the threads will have more to stick to, and we can get rid of the press-fit cap idea.

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

This looks really handy indeed - I've found my little spray bottle cannot keep up with the growth of my tomato plants, so I've just been pouring water straight onto them - not ideal, and erodes the dirt at the roots.

This, looks like an ideal solution :D

Does it perhaps shrink while cooling? And if so - if you pry it off the bed before the normal time, do you think it would 'shrink to fit' on the top of the bottle? I've had that work on my LED diffuser.
