Does anyone have any suggestions for the cleanest printing orientation for the parts? I took the time to re-draw all of Chris's parts in Inventor, mostly for learning, but also because I had to change some parts around. I'm mostly curious about the J2 and J5 spacer where the cable channel/race is. I'm guessing it should be something like this:

* Print the J2 spacer in the to parts upright with supports on the arch.

* Print the J5 spacer flat.
