So, I make all of my mice's habitats myself using bins. The bin cages are great but the one huge headache with them is attaching a water bottle. With the lip around the lid, it's hard to get the bottles to sit at the correct angle for the critters to easily get a drink.

This is a really simple device to attach to the side of the cage. It holds the bottle out away from the lip so it stands upright, which is how to get the water to flow into the tip of the nozzle. The nozzle itself goes through a hole in the bin.

I hope I got the measurements right! Basically all I need to do is drill holes corresponding to the holes in the base and attach the device (you could use bolts but I'm just gonna use pipe cleaners, it's easier and cheaper). Then the bottle can slide into the ring. I'll update this when I get the printer and make one, and let you know if it works! If you make one I hope you show me. :) Depending on the size of your bottle you might have to adjust the diameter of the ring.
