I printed one out of ABS on a Lulzbot Taz 2 (Slicer/Pronterface) with 2 shells, 20% infill, and the pins are nice and snug. It takes quite a bit of force to fit the sections together, but once assembled, move smoothly. This thing is so cool. Love it. Thanks for making it.
The bottom half of the pins on the head printed a little sloppy (no support), but I used a very thick ABS slurry to build them up and smooth them out, and that worked great.
