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...

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 :-)

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

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 :-)

I got fed-up with un-tie-ing the string so often, made HOOK rev 3 with a gap :-) LOL (NB! - use support)

Thicker base, water escape holes, thinner walls,
re-worked interior for better seed flow.

A less-hastily thrown-together hook uploaded.

Apologies for up-loading beta version in error :-(
(I see about 15 people downloaded that version - sorry)

Hi all.

It's been aaaages since I did anything 3DP-related so this little corner of my world has been neglected.
Thank you to all who have made a version and posted pics.
It's really cool to see them all and thanks for making the effort to share :-)

I'm still using my feeder and would make the following changes if I did it again now....

1) print a "holding" piece like Martijndewinter (below) did. LOVE you improvements!! :-)
Then simply pierce two holes in the bottle and hook it in. MUCH simpler. (In fact I ended up doing just that with an old wire coathanger)

2) Make a "hat" for the bottle to keep the water from wetting (and then clogging) the seed.

Thanks again, enjoy your printing adventures!


Works great, thanks!

Without knowing your design, I designed something very simular last year.


Thanks for sharing :-)
Love it!!!

Could this be used with screw top wine bottles?

looks great, what scale do I print this at to fit a standard soda bottle?

Thanks, it was a fun project :-)

I got a little giggle when the print finished, when I saw the number 4 in the seed tray for your revision. ;)
