This is a fairly large USAF Skeleton logo. The standard sized eight ball is intended to give a perspective of the size. Printed on a Qidi X-smart with Amolen Sapphire Blue Silk filament. I imported a stock Air Force .jpg Logo into CorelDraw and created the basic outline using Power Trace. I then uploaded to Tinkercad and created the 3D .stl file attached. Enjoy!
