Uno Ultimate Big Box

I couldn't find a big box to hold the base game of Uno Ultimate along with the 3 expansions (Dr. Strange, Spiderman, Scarlet Witch) so I ended up making one!
This was the very first thing I've designed from scratch and I had zero idea how to make a lid with a latch so I ended up using 3x1mm magnets to hold the lid in place. It works out well for me.
If anyone comes up with any improvements please let me know! As I said, this is the very first thing I've ever designed so I'm sure it can be better.
