Bottle Bird Feeder

thingiverse

It's a bird feeder attachment for bottles. Don't dispose of your bottle where eventually a seabird will devour it and perish. Instead, use it to feed a bird. I printed it with supports. I thought it required these for those parts that attach the ring on the outside to the dish in the middle, but I'm still learning this process, so maybe you can get away without them? Let me know how you fare. It fits bottle threads on standard plastic squash, Coke, or Irn-Bru bottles. I printed it in PLA. If you do the same, don't screw it into the bottle too tightly - I think it would strip the thread. It took about 4 hours to print, but again: I'm still a beginner. I added the openSCAD file. If you open that thing, apologies for the messiness there. I'm still learning. Here's a time-lapse of it being built: https://twitter.com/FlutterCams/status/1217430093661974529 Feed the birds!
