Puzzle Cube

Check out my 3in x 3in puzzle cube that I whipped up when I had nothing better to do. Consider scaling it down, though - each individual piece took over an hour to print and the end result will occupy way less space in your home. You get to decide on the scale for yourself, so just keep that in mind.
