Using this instructable, https://www.instructables.com/id/minecraft-chest/
, I was commissioned by my girlfriends son to make this chest for his brother's birthday.
I found some MDF shelving at home depot for $7. It was perfect at 2' X 4'. I made my box 12X12X12 using 1/2" MDF.
Sorry, no build pics. My son wants one also so I will take build pics for that one.
