I tried to print in HIPS... but I ran into trouble with the axles and cannons. The STL has these pieces arranged in a tight configuration with some inner pieces surrounded by outer pieces. On my TAZ 5, the outer pieces cooled off, while the inner pieces stayed too warm and gooey. Maybe a circular arrangement of the pieces would be easier to print, since they would all cool at a similar rate.
After a few tries to find a fan setting that would work with everything, I gave up and used ABS with a brim for bed adhesion. This worked easily.
