Made this, now has a lid, works great. I did lose the file for the stack able +1/+1 at some point though, my bad. Will include step files for remixing
the large square is for the deck, the small square area is for any token creatures and whatnot, the large hole can fit an oversized mtg countdown d20 and can also fit the smaller d&d d20s, and the smaller hole is for my own designed +1/+1 counters.
The author marked this model as their own original creation.
