Here are some pictures of my Game Master screen that we use with about every reloplaying game.
I mounted the 3D printed screen on a piece of styrofoam to add terrain and details
The 2 braziers in the front, each have a tea light in them (battery operated tea light obviously)
Inside, I have shelves to put miniatures, added some drawers for accessories
Wach wall is covered in velcro to put more custom attachments as needed
Dice tower pointing inside for the game master secret rolls
Dice tower pointing outward for rolls that the game master wants to make public
It took me over 120 hours to 3D prints the parts I needed then about 5 to 6 hours to do the paint job and the terrain.
