About this 3D model

I've been working on this for some time as my first print to grace my 3D printer. Sadly, my printer process was stuck on a back burner, but this file was still done. This is intended to hold a standard square tissue box, has a non-attached base, and a hole in the top for said tissues to come out of. The STL *should* be correctly scaled, but it may need to be broken down to be better printed.
