THIS IS NOT MY WORK!!!! Original file is from https://grabcad.com/library/u-s-s-prometheus-1. This print is VERY well made and has a lot of detail! It fits together so it can be displayed as the ship as a whole or in its "multi-vector attack mode" I have printed this at as large as my printer can handle and at 60mm side to side and both turned out great! Lance Walton did an outstanding job on this design!!!
