Survival Friendly Horizontal Iris Door

The door's settings will be good to go the moment you place the schematic! There are just a few things you will need to do to get it started.

1. You will need to route rotational force into the sequenced gearshift block; make sure your rotational force is spinning clockwise going into the block, or else the door will not open properly.

2. The door has a redstone link with an oak button in Frequency 1. To open it, use a linked controller calibrated for those settings (you can change the frequencies to adjust to your needs).

3. Enjoy!

4. (Leave issues and concerns in the comments and they will be fixed!)
