FencePost Bird Feeder Arm

This bird feeder arm came about when my wife asked for a way to hang multiple bird feeders from our garden fence. After taking some measurements, I designed this practical attachment that not only works great for bird feeders but also for hanging lights, decorations, or small potted plants.

For strength, I used a dovetail cut in Orca Slicer so it can be printed laying down. This orients the print layers vertically, greatly improving its strength.

The fit is snug enough that strong 5kg-rated double-sided tape inside might be enough, but I didn’t want to risk it. I added a hole for zip ties to give extra peace of mind. If preferred, that hole also works perfectly for a screw if you want a more permanent or rigid attachment.

I’ve printed mine in PLA, and so far they’ve held up just fine. Once I upgrade my printer, I plan to reprint them in PETG, ASA, or ABS for better weather resistance.

For convenience, I’ve also included the original STL file without the dovetail, in case you prefer printing it as a single piece in a different orientation.
