A modified version of the model uploaded by rpgweb_101633. I made the cutout wider, so that there is no overhang, when the model is printed on its side (see the second picture). Printing the model on its side is preferable in my opinion, since it makes the print significantly more durable - solving my problem with the holders occasionally breaking.
Main features of the deck holder:
The holder is best used with additional monster HP counters, like the ones provided by rpgweb_101633: The PERFECT Gloomhaven/Frosthaven standee- with optional magnets
