Wine bottle bird drinker

thingiverse

Water reservoir for birds, or other uses, you can also scale it up a little and put it on the ground. It uses a winebottle as a water reservoir. It's made in OpenSCAD so you can easily modify dimensions if you want. You can play around with the customiser a bit, but modifying to far may not yield a usable design. The OpenSCAD design uses the excellent Threadlib library for the winebottle thread: https://github.com/adrianschlatter/threadlib
