I designed this as a Christmas gift for members of my D&D group. It can use up to 5, 6x3 round magnets to hold the cover in place. The hinges can be installed with a short section of filament. There's a top and bottom that have tabs if you have issues with the corners pulling up while printing so you don't have to use a full brim on the whole model. The models all print without support. Happy printing!!!
Edit 4/11/23: Fixed that circle near the hinge on the top of the box.
The author marked this model as their own original creation.
