Attached a bill of materials for the various build options.
I've uploaded the .stl files to Printables as the 3DPrint.social #manyfold instance appears to be down. https://www.printables.com/model/1565794-openbirdfeeder-birdshitcastle3000
Please share a photo if you construct one yourself :-)
Here's a video of the bird using the feeder. Appears to work.
Fyi. Some people showed interest in building one. I'll upload the .stl files and other required materials at a later time.
And the final result placed in the #garden. With the first bird* is already using it!
Such a massive improvement over what we used to have.
*it's a test bird from our coop.
All painted and assembled. Am still not happy with the blue but it's what I had available. In the physical the thing looks good and will stand out nicely in the green garden.
I'm now letting the paint harden a bit. In a day or two I'll give it two layers of transparent weather / UV coating. Then it goes outside and it's up to the birds to destroy it..
OpenBirdFeeder / BirdShitCastle3000 update:
Thinking of the Roman Empire this morning I figured it's actually easy to do a 3D printed slanted roof without waste. Solution is to make it in two parts and print upside down.
So I did that and glued (cyanoacrylate, not sure if that's actually glueing) the parts. I also primed and painted the assembly. Lowest bits are flush with the openings in the sides so no standing water. For summer I'll design a bird bath add-on.
