The file 'Square Opening Bird Feeder Funnel 3D Printer Model' is (STL) file type, size is 393.0KB.
Needed a funnel for the small opening on this type of feeder, so a design that slips inside the square opening with a standard funnel on top was made! 160mm top opening and 105mm high makes it easier now to fill without spilling
