Slinky Mount for Birdfeeder

thingiverse

Tired of squirrels eating all your bird seed? Sliding a slinky over the pole is an easy old-school way to make the post impossible to climb: as soon as the squirrel puts his weight on the spring it simply slides down, causing them to jump off. This bracket prints in about 45 minutes, and just makes it easy to mount the top of the slinky nice and securely to the pole. It is sized for a 12mm diameter pole, and deliberately leaves a 2mm gap on either side (to allow the zip ties to clamp solidly). It will most likely work on poles that are up to 2mm bigger or smaller, but this isn't tested and your mileage may vary.
