This is my Eldritch Horror insert.

The main goal for this insert was to be able to contain the base game and one big box expansion or two minor expansions in the core box with sleeved cards.

I think I succeeded on this since in the pictures you can see the core game plus Forsaken Lore expansion in the same box, and there is a lot of space for another expansions if you make the most of the multipurpose pieces (that can be combined to fit your game combination)

For the tokens and small cards, I use the great design by @mikebourgeault you can find in: https://www.thingiverse.com/thing:2753762 with several modifications. I changed the size and orientation of small cards tray in order to get more space for sleeved cards and other expansions. On the other hand, I also increased the height to store more tokens.

As I said before, you can find some trays tagged with the "Multipurpose" word. You can combine them as you wish. In the pictures some of them are near empty and I could have put some stuff in a single tray and use the rest for different expansions, but in my particular case it was not necessary.

There is space for a couple of dashboards, that can be used as a lid for the tokens/smallcards tray. I made my own design inspired in popular ones here in thingiverse. I included the file, but the thing profile can be found in: https://www.thingiverse.com/thing:3750394.
