Impossible dovetail solutions

Three unique solutions to creating an "Impossible Dovetail" which can be disassembled and reassembled. Recesses on upper and lower surfaces of assembly give refuge to rare earth magnets. Magnets help keep set of three options together. Includes alignment features for stacking as well.

Three solutions:
1. Center of rotation in the center of the square.
2. Center of rotation aligned with short edge of cuboid.
3. Center of rotation at an infinite distance.

These were printed on a uPrint. Still working on how to best print without the uPrint's soluble support system. I've printed this, on my Anet A8, with the dovetail facing upward and the stacking feature/magnet recess look terrible.
