Root Board Game Items Holder

This probably didn't need to be created, but I was looking for something to design. It will hold the cardboard item pieces in place on the board. I put thin, flat, self-adhesive rubber feet on the bottom of mine so it grips better.

v3: lower profile, only 2.2mm in height (pictured)
v4: thicker base, added strength, 2.8mm in height

Both work fine. Print what you prefer.
