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

---

• Start from
• Close into a 2x3 rectangle with
  • two stacks of two tiles in the East positions
  • the South-West tile is of type backslash
  • six tiles are located at the first floor, two tiles (East) are located at the second floor
• Rotate down 180 degrees with a mountain fold the two West tiles, obtaining a 2x2 square
• Slightly open in 3D with the following hingings
  • North-East stack: north side Revert North with South from here on if this is not possible
  • South-East stack: east side
  • North-West stack: west side
  • South-West stack: south side
  • mountain fold 180 degrees between the NW and NE tiles
  • mountain fold 90 degrees between the NE and SE tiles,
  • mountain fold 90 degrees between the SW and SE tiles,
  • valley fold 90 degrees between the NW and SW tiles
• End up with a cube having two stacks of two tiles in opposite sides (West and East)
• The flap in the East stack can be rotated 270 degrees against the upper side of the cube
• Reopen by changing the hinging side in the West stack into the final shape
