Marvel Champion Expansion Insert

This is a derivative of pseudacris314’s design at https://www.thingiverse.com/thing:4776788. I found that my card sleeves didn’t fit in that design so created this modification. It is wider, and shorter to save a bit of filament. I’ve also rounded the corners to fit in the box a little nicer.
While pseudacris314’s design was done for the Rise of Redskull expansion, it did fit in my Galaxy’s Most Wanted expansion box and this design was done with the latter in mind… It should fit in either.
This set also comes with the matching/fitting fixed and floating dividers to go with the insert.
