** Note: I've not installed the part. This part prints 1mm smaller in length and the holes print smaller than the drawing also. I've since processed another 3D drawing, .stl and part from MBI's latest (rev.F) 2D files. But, my second print is the exact same size as my previous. I've not yet learned how to fix and print for tolerance on my bot. Matt at MBI told me to set shells = '0' but upon reading D. Durant's explanation and testing a print with shells = '0' this is not the parameter to adjust. I think it is 'perimeter' but, I need to do other things before I print this again. If you know or have suggestions I'm all eyes to read and try. One of my sons tried placed the part into the laser sheet cutouts and the part fits. The holes are small though. Download STL Generate the gcode/s3g Print. 2/2012 - Update. The file is and was accurate. The printing was by a noob, me, and was not properly setup. I reprinted today 2/23/2012 with experience. The part fits perfectly. But, then we don't need it with all the great upgrades. I just updated this for history and to unmark it as a work in progress. See picture of red part for correct size. FWIW
