A 3 part piston door that consists of pistons facing in almost all directions.

The first button, the one on the left wall, moves the entire wall downwards.
The second button, behind the wall, at the top in the middle, moves the wall to the right.
The third button, the one on the right wall, moves the entire wall to the left and upwards.

I used a variation of the Painterly Pack by Rhodox. The bones are redstone, the angels are redstone repeaters, and the rest is either stone brick or lapis lazuli.

You can use this as an entrance to your mansion, a puzzle in your adventure map, or a doorway to your secret crafting workshop. Just be sure to send me a comment or note saying thanks.
