Parametric Arduino Box for DMX shield

Simple parametric box with hole patterns to fit a DMX shield and Arduino Mega ADK. I use this particular Arduino to use the Maxim USB-host to talk with MIDI control panels. With the AKAI midimix panel (shown) the setup acts as a standard 32 channel DMX mixer. sources can be found here: http://wiki.edwindertien.nl/doku.php?id=modules:mididmxbox

For mounting the back and front panel I use 8mm countersunk pozi1 m3 screws.
