I wanted to create a holder for the screen of the game Mysterium so that it could be place more open than it would go without holders. So that people sitting next to the ghost would not be able to peek over the edge and see the cards.
But, as it turns out, it works for more screens than just the Mysterium screen. (as you can see in the pictures, it also works for the D&D screen from Wizards of the Coast)
I included a left and right STL file even though any slicer can mirror an object so you would only need one of them.
If you want to source (I created it in TinkerCad), drop me a line.
The author marked this model as their own original creation.
