This is the wing/sifter piece for the Comfyer Baby Formula Dispenser machine. Mine broke when we were unscrewing it for cleaning, which kind of sucked. I designed and printed this, which very nearly matches the original design. 

Right now it just uses printed threads, let me know if you want a heat insert version. Note: it would need to be a left handed (reverse) heat insert. This fact is part of why it got broken ;)

It's a bit tricky to print, you will definitely need supports, which can be a pain to remove. You'll also likely want to post process with some kind of food safe coating. I used PETG since I didn't want it snapping again, but PC might be better.
