Business card - Layer selective colour 3D printing
My Very first 3D Printing design and creation uploaded originally to Thingiverse on July 1st 2011
This uses joined pieces of filament the correct length so colour changes happen on layers in the print, the text and objects on the business card are different heights (from 0.8mm to 3mm) so as each layer ends it has a different colour.
