This package includes a front and rear design. The front is slightly smaller and has a slight curve to conform to the grille. These were designed from a Chevy Cobalt SS. Fitment for other vehicles may vary.I print these on my Makerbot R2 with these Settings: .10 LH 222C When printed flat, the surface has an undesirable texture, so I set it straight up and down then lean it back 38 degrees and sink it 1.8mm into the build platform and print with a raft and support. It takes about 2 hours to print.
