could you make a sideways one?

preferably multiple on top of eachother so i could make like a 4x4 piston door?

4x4 or 2x2? 4x4 has 16 blocks in it. 2x2 has 4, if that's what you meant. Anyways, ill try to make a horizontal one. One that is flush.

4x4 or 3 or 2 high and 4 wide

cool goodluck post enough detail so we can recreate it please

4x4 is very very tricky if not impossibe. But i'll try the 2 high and 4 wide. Ill post as soon as i finish
