[previous configuration] [up to this 3D shape] [next configuration] ― Configuration code: RRUvDvLvDmUmLv

---

• Start from
• Rotate about the vertical axis such that the flap tile points north
• valley fold the two southern horizontal tiles together with the north vertical tile, simultaneously fold the vertical wall of two tiles such that the common hinge moves towards west
• We arrive to a 2x2 square with a stack of three tiles in the south-west position, stacks of two tiles in the north-east and south-east positions
• reopen changing the hinging of the bottom two tiles in the south-west position
• continuing with the movement we arrive at a 2x2 square with a single tile at the south-east position, stack of two tiles in the remaining positions and a single flap tile that sticks out north of the square
• reopen changing the hinging side of the south-west stack and turning the flap tile above the stack of two tiles (north-east). The north-west tiles hinge around their west side, the lower of these tiles must be forced on top of the east tiles (this require some stretching)
• We arrive at the final shape.
