This model is definitely a conversation piece, not as simple as it looks to print, but well worth it. I recommend using supports and a lower speed setting than what I used (85mm/s) 35 -45 mm/s would be better. p.s. I originally had trouble with these files ( I only got a base and one arm) but I ran them through meshlab and erased the duplicate vertices and everything popped right up! special thanks to EUGANT for his help with this files.
