Machine Features: 

I have created a 5x5 piston door that opens in 0.75 seconds.
It has a size of 1530 blocks (15 x 17 x 6).
Closes in 0.45s and is fully seamless.

How To Use: 

The input is spam protected with the help of an external circuit.
There's two versions of the door: on with and the other without hallway blocks for better visibility.
I have also reconstructed the piston layout.

To activate, one would activate and deactivate the input lever, the second version with hallway blocks clocks automatically.
