This is a simple Hazard Stripes Pattern to be used as a stencil / template for airbrush work.
Height is 0,1mm so you need to scale in one axis to the height required. I suggest at least 2 layers for stability/coverage. The thinner you print it, the more flexible it will be at the end for curved surfaces.
