Stackable Box System for Screws and Nuts

Remixed with new Features and box sizes:
=================================
Remix -> http://www.thingiverse.com/thing:1090191


Intend to organize screws. Take 1-2-3 through the front or dump out a Hand full on the back of the box...
Box on pics is filled with 500 Screws M3x12mm.
i have to replace the wall in the middle for nuts, spacers and longer/bigger screws. will upload some more boxes wich fit in the System soon...
the stand has holes for wallmount, but this Version is not stiff enough to hold more than 1-2 boxes if filled with heavy stuff like screws. update for wallmount with stiffer design also comming soon...

UPDATE:
i´ve added small boxes with 2 and 3mm Slots V2. (removed 2-7mm boxes from yesterday cuz they didn´t fit exactly at the back and need Support for the slot)
This versions are good for M3 Spacers and M3 Nuts.

Added: V2 of 4, 5, 6 and 7mm Sloted Boxes and the more stable wallmount Version of the stand. (not printed yet but slices nice
