While not a remix of a design this was heavily influenced by Johnny_Tsunami version of the box insert. That can be located here - https://www.thingiverse.com/thing:5411665.
This fits all current expansions.
From his basic design:
I made the spaces larger so that they can fit the Unstable Games sleeves.
Created a space under the large cards for more dice, also made the spaces bigger to hold 16mm dice.
Made the dice tray removable.
The author marked this model as their own original creation.
