[casper] Roach I Mechanical Drawings

[Joe Greenberg]

Can we obtain any mechanical files for the Roach I Board. 
I have seen a STEP file for the ROACH II, so perhaps there is one for 
the ROACH I also.
Acceptable alternatives are:
STEP File 3D model
AutoCad .dwg or .dxf 2D files
I already have the Gerbers which do not have the required information.
Thanks
