Supercharged 3x3 Piston Door / Minecraft Tutorial and Explanation

Pretty cool 3x3 that I made quite a while ago with Hampter. Closes and opens super fast while being seamless and relatively small. 3 x 10 x 11 = 330 blocks Closes and opens in 0.3 seconds (0.25s new terms) Version 1.16+ Only works in Java Edition! I use the G4mespeed mod by G4me4u for smooth piston animations:    • Minecraft G4mespeed mod for 1.14+ w/ tutorial
