3d mail slot

So I have a mail slot on my house. Not like your normal one on the door but this one leads into a chute that goes through the wall. Anyway I got sick of walking a whole two blocks to my nearest blue collection box so after the idea sat in my head for a year I finally pledged to find or build a basket type thing to catch outbound mail. I thought I could buy one online but I couldn’t find anything. So since I have no experience in 3D modeling I went to the robotics team at my school and then helped me design it and then I printed it at my school for free! I stuck a label on it and voila!

What do you yall think? Legal? Annoying? You can still access the regular mail slot.
