The "Impossible Dovetail" in cube and tall form, 3D printed in PLA

cults3d

I crafted these wood cubes on a bandsaw in my high school wood shop about 45 years ago, but they were much larger than this version. My shop teacher would meticulously measure each finished cube to ensure it was precisely 4 inches by 4 inches by 4 inches - a time when teachers expected exacting results. This 3D printed version is significantly easier to create and measures only 40mm by 40mm by 40.2mm (.2mm taller than intended, I hope he doesn't notice). Unlike its wood predecessor, it requires no hand cranking, motors, glue, or other manual labor - at least not yet.

UPDATE: I've added the taller versions of the two pieces as requested by several fellow 3D printers.
