Straight Stacker 1x1 2 layer input & output

[twin pebble]

This is the most efficient 1x1 stacker blueprint that excepts 2 layers of input. I think.
(I worked on this for like 3 hours trying different layouts and I finally made it work)

2 inputs optional or required?

Good job on using the straight stackers. Extra challenge using them.

Oh mb, I had a brain fart on how stackers worked

Forgot you need 2 inputs anyway. i was thinking 3 inputs for one stack operation so you could have an optional side
