3D Print Square Light Bulb

Square peg in a round hole? How about threading one? I have a strange fascination of making round things square. I thought of this great challenge to make a square light bulb, but also have it thread into a round socket. No CAD software used or bolt generators. Careful measuring with calipers and a good eye allowed me create the square threads. The end result it threads into your standard light bulb socket. I only wish it could actually illuminate. The “GE” writing was painted by hand.
