I had already printed the excellent baskets from tjdesign (https://www.printables.com/model/252166-everdell-resource-baskets-and-lids) that you can put out on the board, but I wanted something on top of them to hold the meeples and some card trays to make lifting the cards out easier. Card trays should support sleeved cards. All of these fit within the existing plastic insert for base Everdell.

My print in the photo is hashed as I print without bottoms/tops/walls to save on filament.
