The disorganizer consists of two parts that can be printed without additional supports (with a bit of luck and enough cooling).
Part A has sockets and part B has plugs to glue one of the sides in place.
I'd recommend printing the the last top centimeter of part A before going for the whole piece. This way you can check if your printer can handle the overhang.
I haven't tested for maximum weight. Don't throw bricks in there.
The author marked this model as their own original creation.
