drill bit storage

I spent hours looking for a drill bit tray that'll suit my requirements as i have over 70 bits of various sizes and i need the tray to fit in a toolbox. So, i designed this simple arrangement, my drill bit length range from 50mm to 160+mm .
It could be used for screwdrivers and other stuff to keep the area tidy.
it's still a mod in progress with height etc. . size is about 200x200x30mm..
