Got my laser module in the mail and wanted to try it out so I took some measurements and came up with this. I added two 4mm threaded holes on each side for some set screws (I just happen to have like a hundred lying around). I won't need the set screws on my machine as revision 3 (photo) is a nice tight fight. I had to make another revision as the custom box my CNC sits in the lid won't close with the laser module in. I added that file as well, dropping the laser down 10mm.
