I am attempting to make some modifications to the Hexagon hotend mount plate but the correct CAD file is nowhere to be found. If you follow the source links on the product page it takes you to http://devel.lulzbot.com/TAZ/accessories/fangtooth_guppy/. The STL and the FreeCAD file at this location do not match the production mounting plate. The STL in the TAZ 5 download directory is correct but there is no corresponding CAD file. I asked this question in the TAZ forum with no success, I am hoping someone here might know where to find this elusive CAD file.
