I needed a feeder for my aviary so I created this one. It is mounted at the end of a 40mm transparent tube filled with the seed so you can see the level of seed decrease as the birds consume it. Perfect for my case where I am able to observe the amount of seed through my window.

Inside the body there is a cone that distributes the seed evenly.

Print with PLA or PETG, no special settings (15-20% infill would do)

For MINI+ users there is split model of separate body and a the perch, which you need to print four times and glue together.
