Created for a friend that is passionate about the Simpsons, simple 16 minute print on the X1, 26 on the A1. Single colour 3mf as a full colour would have been 5 plus hours for a single head. Use the raw file if you would like to colour the print. eyes add double the time as the single print. Perfect fit for a schrader valve. Surprise your friends and sneak these on their car or bike. Thanks for looking and Happy Printing
