Files are provided as-is.
STL Files at 1:1 scale, these files have been designed to be scaled five times larger and may work at other scales. Many of the parts are generated from the supplied SCAD files. These SCAD files were my tweaked versions of projunk files. I added fillets to the top of the pins and altered some dimensions / tolerances. Original projunk files can be found here:
The STL files are zipped up into their various colors. There is a PDF document containing the required quantity of each part. For more information on the original kit and build instructions visit here:
Most bricks are printed at 15% infill.
Axles are printed at 50% infill
Gears and pins at 25% infill
I also used a Twoolhead for the Taz 6 which saves printing time by printing two parts simultaneously with one printer.. see pictures or check out his link:
