Box with drawers parametric

Box with drawers. Completely parametric, you can choose the number of drawers and the compartments in them.
On the lowest drawer “A”, the height is selectable. The other drawers' (B) height is equal to the height left (Box height - Drawer A height) divided by the number of drawers - 1. 

In each drawer, the first compartment is always the full width and you can change it's length and the rest of the drawer is divided by rows and columns.

Box's shell must be printed with the backside on the bed.
