This is an insert that fits into the upper deck's slot. This allows the bottom deck slot to contain the unknown cards and the upper deck slot to contain the revealed cards. Why is this needed you may ask?!
We like Gloomhaven and our eyes aren't what they used to be... We modded the game with different parts, standees, minis, and such. People on the far end of the table can't see the monster turn abilities or their base card. Putting the face up turn card higher up allows people to see it better.
It was not necessary to create a whole new design as what is out there is fine, and the insert is a much quicker print. Also, people with existing stands can just print and add the insert if desired.
I printed the stand and insert at .3 resolution with 40% infill density. It was designed to fit a tiny bit loosely. I cut off some of the corners and changed a few angles to allow for a better fit.
I would like to thank richifever for the very useful deck holder and ZenziWerken for the sweet skull image. Also, I would like to thank quizzcode for his modification to richifever's deck holder that keeps it from tipping over. I included quizzcode's modded deck holder as that is what I designed for.
