Here is a Mechanical Piston, it works when you pull the lever. I got the idea from buhjaboy's awesome chest: http://pixelpapercraft.com/papercraft/53a97d37a12138d539000059/mechanically-opening-chest-standard So credits to him, and Gootube2000 for the base of the lever. Also credits too Lostminer and Obsidianaxe for the grass.

You can choose if you want a sticky or normal piston, and if you want normal or alpha grass.

Thumbnail coming soon, batteries are too low (lol) But you can watch this video of it, wich I could just made in time: https://www.youtube.com/watch?v=7EdXKtDdYvA

Hope you like it :D
