The file 'DIY Chicken Feeder 3D Printer Model' is (stl) file type, size is 189.6KB.
I made this to attach to any food grade plastic bin you might have, simply scale to size, print, cut or drill a hole in the container you'd like to use and superglue this dude on there. I'd suggest setting the wall thickness to 4mm and scaling to 75cm across for chickens.
