This piece divider fits the Super Stacker, Crayon Box found on amazon or in Walmart. (I found them at walmart for $1.00 each) It has 8 spaces to hold pieces with the cut out for the metal Key Forge keys you can buy on amazon or win at local chainbound tournaments.

I printed it with a Creality Cr-10s Pro with 10% infill.
