Its cool cube that can hold a double sleeved commander deck with plenty of extra room for tokens

what is needed
1 top
1 bottom
4 edges version 1
8 edges version 2
8 corners
6 hearts
6 heart coin
pegs as needed
16 6mmx3mm magnets optional
glued together with all purpose construction adhesive (any thick glue should work)

notes
edges version 1 is for sides
edges version 2 is for the tops and bottoms
The hearts are pressure fit in to the coins (i used a table vise)
There is plenty of holes for the pegs or magnets. I only used one peg per part to keep it in place while the glue set.
use rubber bands to hold it while the glue dries lots of them everywhere
black paint helps the lines stand out
