Tech Tool Tray upgrade

If you look at the second image in the gallery, you can see the original tray this harbor freight tool kit comes in - the gray part is both flimsy and inconvenient. My upgrade is better to hold the bits and can be stored vertically without any spillage.

The only improvement I want to try is to decrease the amount of filament to fill so that it takes less than 24 hours to print at high quality/high def. Anyone who can do it? Post it here as a remix!
