Anyone Use 6mm Baltic Birch for your frame material? I have a few pieces of high quality birch plywood left over from another project, access to a Lasersaur laser cutter (48"x 24") for a few weeks, and want to try building an E3D Bigbox. I am learning inkscape and have downloaded the SVG files from here: http://www.thingiverse.com/thing:1844896 Many thanks to Alex9779 for the SVG files! I have been unable to open the DXF files in inkscape and when I convert them, the scaling is way off. It looks like the BigBoxXL: http://www.thingiverse.com/thing:1753550 Uses 6mm material. However, I can't open the files in inkscape to edit, and I think the increased Z height would require a larger laser cutter than I have access to (& more plywood). I've been attempting to edit Alex9779's svg files for the increased 1mm thickness. And getting pretty frustrated. If anyone has already altered the BigBox frame to use 6mm thick material, and has SVG files completed, I would greatly appreciate a link; or any help you could give me. Thanks!
