The challenge

The owner of a 10th-generation Honda Civic sedan wanted a trunk spoiler shaped to the car's own trunk lid. The spoiler runs the full width of the trunk, which is longer than a printer's build plate, and it has to follow the trunk's curve from side to side.

Our process

  1. 3D scanned the rear of the car, including the trunk lid.
  2. Modelled the spoiler in CAD on top of the scan, following the trunk edge and the notch in the middle.
  3. Split the spoiler into sections that fit the printer and printed them in red.
  4. Joined the sections into one full-width piece.
  5. Test-fitted the spoiler on the trunk lid.

The result

The spoiler runs the full width of the trunk lid and follows its curve, with a notch in the middle that matches the trunk. It was printed in red sections and joined into one piece. The photos show it test-fitted on the car, before any paint or final mounting.
