It was recently discovered that the original Cylon Centurions were 3D printed in mass production. The Centurion leader was always printed at the same time as his 2 subordinates (and he was always done first) This formed the trio and were almost always assigned to a single Raider.
To build 3 - 3D printers, you will need 6 horizontal supports, 6 vertical1, 6 vertical2, 3 build plates, 3 nozzles, and one each of the Centurions.
Use supports on the centurions and leave it attached and glue all to the build plate. Paint some parts gold on the center Centurion and silver for the other 2.
3/16/19 I added build plates with the 3 partial Cylons as one piece so the support can be displayed easier. Will post pics soon!
