Machine Features: 

It is a piston door 3 by 3 that opens and closes when pulling a lever.

How To Use: 

It is a door that opens and closes on request through lever. All nine blocks open through these logic: the pistons grab them and move them. I have used observers, sticky pistons, pistons, note blocks, blue wool, red stone dust, smooth quartz blocks, red stone repeaters and a lever.

Comments

Promotion request builds should be outside of Visitor area. Visitor area gets cleared at least every 2 months. A dangerous place to put promotion request buildings.

Besides that a 3x3 door is a bit simple for a rankup to Tinkerer rank. Feel free to use '/challengeboard' or '/challenges' to get a list of creation which are of enough complexity for a rankup.
