As part of my plane to create a simple, solid Arducopter frame, I have had a number of parts laser cut in 2mm 6082 aluminium from the original Arducopter frame design by the DIYD team.
The parts have come back a little more "bashed up" than I expected, but apparently that's normal, they just need a clean-up with something abbrasive.
I had trouble opening the DXF files in the SVN. In the end I opened them in Microsoft Visio, saved them as Autocad files and then exported them back into DXF files from within Autocad after I tweaked the legs etc not to need the dome. The laser cutters seemed to need the DXF files in the 2004 format attached.
I can't verify anything fits (they've just arrived and I'm in the office), but for those feeling brave the DXF files I used are attached for anyone that wants them.
