Tiêu đề Khay đựng thức ăn cho chim thân thiện với môi trường

I designed this bird feeder together with my friend Aelita Zhuma (Instagram, Facebook), it is her initiative and creativity. It has been tested and works well for feeding small birds; large birds will not be able to sit on the edge. Thus, those birds that are important for the urban natural balance are fed. You can use any 0.5 bottle and only need to print 2 parts. Or even one, if you don’t use a special cap with a ring, but simply tie it around the neck of the bottle.

You need to make a cutout in the bottle like in the photo and just fit the slit of the piece onto that edge, no glue required. Print without supports from any plastic, but it is worth considering that PLA can soften in the sun.

I used the threaded part of the bottle cap @3DAcademy, thanks to them!
