1x1x2 Stickerless Rubik's Cuboid

A simple one piece print that I used as a sort of warm up to my bigger 1x2x3. If this doesn't work on your printer, then you can rest assured neither will my 1x2x3. I mostly made this as a test of how well my printer could print a pin that reaches into a neighboring block, where it gets wider effectively locking the two blocks together while still allowing them to turn freely. It is not a hard puzzle, but it is one that lots of my friends enjoy because of it's simplicity.
