I found This RAMP Enclosure http://www.thingiverse.com/thing:10926
and Print it out without knowing it was meant for RAMP 1.3 wasted 10 hours to find out it was not fit my RAMPS and Arduino Mega. Thanks to the Author providing scad file so I have it modified to fit RAMP 1.4
I never use openscad before so it just my silly hack moving thing around so no openscad file is attached to embarased myself ;)
The PCB mount rails was centered and shorten then moved to support the Arduino mega instead the RAMP this will eliminaed the need for dremel work after print, cutting a hole for accessing the reset button, moving the holes on the left cover to accommodate the connectors that was moved from the original thing.
EDIT: Important I changed the fan mount from original thing. the Fan I use can be found at http://www.digikey.com/product-detail/en/MC30101V1-000U-A99/259-1550-ND/2757778
This new fan produce a lot more airflow than the one used in the original thing.
EDIT: I uploaded SCAD file so you can improve or adapt it according to your needs. the original SCAD using dxf file in linear exrude statement while mine was modified to be a self contained so there is no dxf file included.
Simply print it then put all electronic in to the box.
