The file 'Small Shelf For Stuff 110x110mm 3D Printer Model' is (stl) file type, size is 26.6KB.
There are no special Print settings.
It is an easy Print with no supports needed.
Maybe you just have to turn it on top in your slicer Programm.
The Size of the Shelf is 110x110mm.
I designed it for the Mario Box.
