Mail Sorter for Gridfinity

This organizer is large enough to hold paper upright, and fit envelopes, magazines, etc.  I made it for my entryway to place mail in here, since I will never look at mail when it is piled up.  Easy to see everything at once, and easy to make multiple for everyone in your house so that they always know where their mail is.  Larger slot on the end for a larger notebook (school-sized). 

This is my first model ever so please boost if you like it!!
