Summary

A bird feeder hanger that can be mounted on a railing beam with dimensions 51x128mm.

The dowel should be printed horizontally, with 100% infill. I turned it with a drill and some sandpaper to make sure it was round, and it was a good press fit.

Requires an M3x12mm bolt + nut, and a carabiner.
