3D Printer World has rolled out three design contests and a fourth is a GrabCAD Challenge. Each contest will award $15,000 to the first place winner, with second and third place honorees earning $3,000 and $2,000 respectively, bringing the total prize pool for the four competitions to $80,000 in cash – the largest sum ever awarded in a 3D printable design contest series.
