Insert from Gutshot games / turbogoof's blank template. Fits Mindbug: FIrst Contact + 2022 Promos, all sleeved. I used UltraPro Eclipse standard sleeves i had laying around.
Fits with the folded instruction booklet on top plus the two life counters below the cards, also included a version without space for the instruction booklet.
I like the look of hex infill, so to print, placed a couple of modifiers to remove top and bottom layers and leave exposed hex infill with 10 or 15% density in the card bays to get the result shown in the pictures.
The author remixed this model.
