The stock insert is pretty good overall, but it needed just a few tweaks. These items were made to work with the stock insert.

Items to print:

1x - Resource_Tray
1x - Dice_Holder
4x - Player_Tray
1x - Caravan_Upgrades_Card_Tray
1x - Small_Card_Platform

Notes:

Resource tray replaces the big tray they give you that is supposed to mix up the resources. I like separating out the resources, so I made this tray. It's slightly snug, but holds in place very nicely (almost like it snaps in). You may need to take the tray out of the insert by lightly pressing on both sides via the side indents, but it isn't much.

Dice holder is a bit unnecessary, but I liked the idea of the dice being snuggly in place.

Player trays don't include room for the caravan token, but they sit nicely to the side of each tray. A pretty cool design by them.

Caravan upgrades card tray is just to make it easier to take the cards out of the side area with the dice and small cards. This is only necessary if you want to sleeve your cards. All the cards fit in the main card section without sleeves. This tray is pretty tight to the Dragon Shield Clear Matte sleeves I'm using, but I don't see any damage. Honestly, this doesn't even need to be the caravan upgrades, it could be the starter cards, or whatever configuration you see fit.

Small card platform is an odd one. I was having trouble getting the small cards out of the well on the other side of the dice, so I made a little platform to avoid having to struggle to get a fingernail under the last card. If you've found a better way to store these cards and don't need this, do without it.

Lastly I want to give a small shout-out to the developer(s) that created the board game insert toolkit for OpenSCAD that I used to make this organizer by giving a link to it. They made it very easy to use and the documentation is fantastic.
