Tetracubes are a three-dimensional version of ‘tetrominoes’… That is all of the possible ways to join four cubes together in 3D-space.

This includes some of the ‘Tetris’ shaped, but allows for rotation - so the L & J tetracubes are considered equivalent.

The models do not need supports and can be printed with standard settings. Advanced printers may want to iron the top surface to create a smoother look to the puzzle pieces.

For compatibility with all of my other models, print a 100% scale.  If you scale any model, please remember the scaling factor and apply it to all models if you'd like them to be compatible.
