I was gifted a inexpensive incubator and found that i was not able to efficiently incubate quail eggs. I am a bit of a newbie (to quail and 3D modeling). Print 3 of the main assembly pieces and the 1 plate of the pins. Piece together with CA glue (that's what i used) or whatever else your comfortable with. This turner will hold 33 eggs i put 32 eggs in it and of the 32 i only had a problem with one egg not turning. Its far from perfect but it is functional. Thanks!
