Hanging Shoe Rack

I designed this simple hanging show rack that can be printed with PLA. For reference: shoe size in the picture is EU 40 the second one is 48 ½.The Print is split it up into two parts. The Main Body, and 4 Connectors needed to hang up the shoe rack.I used nuts and screws to attach the Connectors to the Main Body, but you could maybe get away with glueing them in. I had the following Stuff laying around, so I designed around it.I did not link the M3 Nuts from Makerworld, as I am not 100% sure they would fit into the designated hole.Assembly is pretty easy, but I attached an Assembly Guide anyways.I'm open to any kind of feedback, as I am pretty new to designing.
