Shelf with drawers

This is my first ever attempt at designing my own thing from scratch. I am very much open for ideas on how to improve my design.

The walls are printed separately so you can choose which wall design you want and so that they can be switched out with the other wall designs you want instead or if you want to completely remove the walls and just have the drawer as one big container. I would recommend only printing the drawer with wall support as you never know if you suddenly want the drawer split up. If you know you don't need walls and you want a smooth surface in the drawer then go for the Drawer with no wall support.
