This really is a wonderful one piece bird feeder (for smaller fowl) that's a thread to adapt a 2 litre soda bottle as the seed "hopper".
(after many requests, I made a liquid feeder variation for hummingbirds and nectar eaters. It is at...
There's additionally a small "hook" you can paste/epoxy onto the foundation of the soda bottle to let you hang it in a tree.
Rev 04g is (hopefully) the final variant of the model :-)

Could Not resist two more small mods...
1) Holes enabling seed out made somewhat bigger and interior cone made a little steeper (I found rougher feed getting stuck frequently)
2) Place a taper between the narrow vertical cylinder and also the thicker threaded part to prevent the wreck of overhanging print.
Unfortunately I'm experiencing warping on the outer ring :-(
(ABS at 230 deg C, bed at 115 deg C) - any thoughts to resolve/prevent are most welcome :-) Thx

After much frustration at filling the PET bottle with feed through a too-narrow funnel, I made a double-headed-thread to simplify life. I use a cutoff PET bottle as a funnel and screw both sides into the brand new piece. Simple :-)

I got fed up with un-tie-ing the cord so frequently, made HOOK rev 3 with an opening :-) LOL (NB! - use support)
Thicker foundation, water escape holes, thinner walls,
reworked inside for better seed flow.
A less-hastily thrown-together hook uploaded.
Apologies for uploading beta version in error :-(
(I see about 15 folks downloaded that version - sorry)
