Push Pull

### Push Pull

Push-pull is a cubic box with swing door in one side. Each doorhalf has a wing on the side of the axis. This means when a door opens the wing sweeps in the 3x3x3 volume of the cube. Five polycubes must be packed so the doors can close. No trivial task, imagination and perserverance are needed.

### Printing Instructions

Print two of the door lids and one of the other files. After printing, slide the lids into the box. Make sure that the “push” text is on the outside of the box and the longer, smooth part of the lid on the top. After that you are all ready for puzzling.
