I was looking for the insert for base Pandemic game that would hold sleeved cards and all the pawns in place vertically. The design is mine except the outer dimensions which I took from https://www.thingiverse.com/thing:3412724 - and at least for my edition of the game - the insert could be 2mm wider.
The Lids should be printed with 0 top and bottom layers and infill set to honeycomb (or whatever suits you)
Depending on the accuracy of your printer the edges of the insert might require filing down a bit so that the lid will close easily.
