A torus made from pieces that are the union of cubes. 5 pairs are needed to build the torus.

# Construction
Print five pairs to construct the torus.
Overlay mirror image pieces and then insert the final cube to lock into place.
The pattern will wrap around into a torus.
I needed to use needle nose pliers to squeeze the final locking cubes into place.
