Lucky Loot Crates By StealthyExpert
 
These are new items that players can place and the contents of the chest will be randomized each time the same chest item is placed on the ground
and opened or broken by the player this also works in versions of minecraft 1.9 and up so its pretty version friendly ;) I am in the progress of finishing a mcedit filter to recreate these so you can expect to see that soon for sure :)
