This command is also 100% made by me and it lets you make scaffolds by sneak-walking. First, type in chat /scoreboard objectives add sneakplace stat.crouchOneCm. After that, just paste the command I included below into a command block and ur all done, just sneak and walk to enable! Enjoy! {PS. After ur done and want to stop it just break the whole mechanism and type in chat : /scoreboard objectives remove sneakplace}
