automatic bird feeder

I have desigend an “Automatic” bird feeder.

Simlpy screw in a normal PET-bottle and it will automatically refill the feeder.

Some notes of interest:

• PET-Bottle diameter can have max. Ø85
• Bottle must me cut to a length of appr. 10-11cm
• Only “small” feed is possible without clogging, e.g. Sunflower seeds

• Windows, sitting bars for the birds and roof battens must be glued to the main parts

  (bars and roof battens must have the correct orientation, keep in mind)

• There is a 2-part design with just the roof as an extra part to screw on and there is also

  a 3-part design with bottom, middle and roof. (see photos)

• For the 3-part design you have to press in 6 heat inserts (M4 x 8 x 6mm or shorter) and

  screw bottom and middle part together with 6 screws (M4 x 12mm or shorter)

• There are some drainage slots on the bottom to prevent water from staying inside

• For best print results, just use my settings (on some parts I´ve made fuzzy-skin, manual supports

  or some other special settings)

Each of the parts can be printed on the A1-Mini as well!! 

Happy Feeding!
