Bird Feeder (with soda bottle thread)

See the feeder in use by its intended customers :-) https://youtu.be/Q_Fag1fDXCo This is a lovely one-piece bird feeder (for smaller birds) that has a thread to accommodate a 2 litre soda bottle as the seed "hopper". (after many requests, I made a liquid feeder version for hummingbirds and nectar eaters. It's at... http://www.thingiverse.com/thing:260695 There's also a little "hook" you can glue/epoxy onto the base of the soda bottle to enable you to hang it in a tree. Rev 04g is (hopefully) the final version of this model :-) Tweet tweet enjoy :-) UPDATE HISTORY (oldest at the bottom) 2014 03 30 ii Couldn't resist two more little mods... 1) Holes allowing seed out made slightly larger and inside cone made a little steeper (I noticed coarser feed getting stuck often) 2) Put a taper between the narrow vertical cylinder and the thicker threaded portion to avoid the mess of overhanging print. Sadly I am experiencing warping on the outer ring :-( (ABS at 230 deg C, bed at 115 deg C) - any ideas to resolve/prevent are most welcome :-) Thx 2014 03 30 i 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 now use a cut-off PET bottle as a funnel and screw both sides into the new piece. Easy :-) 2014 03 01 (318) I got fed-up with un-tie-ing the string so often, made HOOK rev 3 with a gap :-) LOL (NB! - use support) 2014/02/23 (199) Rev 04g 2014/02/21 (157) Rev 4e 2014/02/9 (72) Rev 3 2014/02/18 (68) Rev 2 Thicker base, water escape holes, thinner walls, re-worked interior for better seed flow. 2014/02/17 A less-hastily thrown-together hook uploaded. 2014/02/16 (15) Apologies for up-loading beta version in error :-( (I see about 15 people downloaded that version - sorry)
