I made this model from the two sources. I cleaned up the original Vader Buddha mesh, and then had an idea when i was printing off the Mark 50 head... so here's the iron buddha. It slices fine in S3D (they have the most finicky slicer, imo). Definitely need supports for his chin. I used them on his arm, the hand in his lap, and a little on the back of the head, but i don't think those ones were necessary there... I printed him in translucent red PETG from Makergeeks.com. It came out with a nice shine/sparkle, and printed very clean.
