Bottle Bird Feeder

It's a bird feeder attachment for bottle.

Don't throw your bottle out where eventually a sea bird will eat it and die. Use it to feed a bird instead.

I printed it with supports. I thought it needed this for those bits that attach the ring on the outside to the dish in the middle, but I'm pretty inexperienced with all this, so maybe you can get away without it? I'm not sure - let me know how you get on.

It fits bottle threads on standard plastic squash / coke / irn bru bottles.

I printed it in PLA. If you do the same, don't screw it into the bottle too hard - I reckon it would take the thread off. Think it took about 4 hours to print, but again: I don't really know what I'm doing yet.

I added the openSCAD file. If you open that thing, apologies for the messiness there. I don't really know what I'm doing.

Here's a time lapse of it getting built: https://twitter.com/FlutterCams/status/1217430093661974529

Feed the birds!
