This insert is designed to fit Munchkin in the photo caddy.

This design along with several others have OpenSCAD files available on my GitHub

Made specifically to fit Photo and Craft Keeper 4x6 inch storage bins (made by Simply Tidy and others), this collection of board game inserts allows you to ditch the boxes and consolidate your collection. For added convenience, each insert can work with Boardgame Barrio's printable box covers or covers you print yourself.
