I built a compact 2x3 elevator door, the door is is near seamless. I might submit it to community boats, likely identified as class 1.

I also discovered a (sometimes working) opening and closing turret head. (3x3)

If pistons can snap in place when extended or retracted, detect when they are extending backwards or at any angle beyond 0˚, and bind to eachother when stacked, the lag produced would cease.
