SummaryUser forest66 asked for a cut up version of dc42's Duet enclosure. Here it is, quick and dirty, done using the puzzlecut library (http://www.thingiverse.com/thing:35834) by nothinglabs. I did not print this myself. Whether the puzzle parts have enough clearance, depends on your printer and its calibration as well as extrusion factor. If you don't want to fiddle with that, try adjusting the kerf variable in the OpenSCAD file, I think. Remember to install the library mentioned above first. Hope this helps!
