It's a racing spoiler for mini cars that will make your car look great !
For cars that are the size shown in the photos, I recommend printing at 100% size. However, I recommend measuring your car and printing the spoiler to the size you need.
From my experience, the layer height should be as small as possible, ideally 0.10 mm, to maintain detail even at a small scale.
To make it easier to remove the supports, I recommend printing vertically.
