Gazebo Bird Feeder

This is a gazebo-style bird feeder for small birbs such as finches, sparrows, nuthatches, chickadees, etc.

I liked the classic design of the original, much thanks to the creator, but I wanted a single roof piece, so I created that and then made some other additions while learning Blender. The design is virtually identical to an old wooden one I have but with a bigger openings that shouldn't get jammed up like they constantly do with the wooden one.

It has 1.2 mm wide tracks in the arches to slide in 1.1 mm acrylic sheets, or printed panels. I've included a panel that is 1.0 mm thick, which is purposely thinner than the track width to allow for 3D printing inaccuracies. You can print a grid panel by setting the top/bottom thickness to zero and the infill pattern to grid in your slicer. You can of course use any other infill pattern, such as the cross pattern shown in the photos.

The assembled model is 183 mm x 159 mm x 159 mm and weighs about 333 grams. Additional material will be needed for the supports to print the roof.

Printing 

I printed mine in PETG, but PLA would probably be fine too. The PETG should be better able to withstand the elements, so that's what I used.

The roof needs supports. I printed mine with a layer height of 0.12 mm to get a smooth slope on the roof exterior, and with that small of a layer height I was able to set the support overhang angle to 60°, and the unsupported sloped areas of the interior were just as smooth as the exterior. The supports were provided only for the flat areas around the perimeter and at the very centre and the roof.

The pillars also need a tiny support platform for the peg at the end.

You'll need to print the roof, arches, benches, and base pieces, but the other pieces are optional. With just those pieces, no glue is even required, but I'd still recommend glueing. If you add the pillars, they will need to be glued to the arches and/or benches.

In all the photos of the feeder—empty inside and filled outside—there is actually no glue applied yet, but the pillars can fall away as soon as I lift the roof, so they'll need to be glued.
The photo with the sponge doesn't have the pillars installed and has a smaller base that I had scaled to 91% to fit on my Flashforge Creator Pro. I realized that it was too small, so I put my Ender 3 V2 back into service to print a full-scale base.

UPDATE 2026-01-24: The roof has been cleaned up with the removal of the internal walls for the sides of each of the six roof panels. These would cause print paths for the walls to have some acute angles which would cause more pronounced ringing and bulging effects. The walls should now be printed with only obtuse paths.
