Bird feeder with threads for plastic soft drink bottle

thingiverse

Last year I`ve printed feedr designed by bencina garden friends were quite happy, just there was a problem - during rainy or foggy days, wetness makes food sticky and distribution stopps. So looking https://www.thingiverse.com/thing:2676251 as an inspiration I`ve made my version from scrach using freeCAD. Here are major changes I`ve made after observing my little "clients" in actionr: - outer diameter bigger approx 5mm it seems that makes it more comfortable for birds - main area of a feeder a bit higher so birds drop less food - feeding supply holes are lower than the edge also, less dropped food - additional fences inside feeder makes feeder more sturdy and birds are digging out less food - redesigned neck to make it a bit cone shape, can be used with various food types without a friction - cone inside is much higer helps to redistribute food evenly among 4 sections - neck much higer so enough space for a roof - redesigned threads made them higher so bottle neck always fits P.S.roof`s hole is almost same diameter so needs to be a little bit sanded but not too much so can be attached keeping it hermetic This version is fully functional, but I`m open for ideas for further improvements.
