3D printable spray paint stencil, demonstrating bridging parts of the stencil together in a way that allows for underspray to do things that you couldn't with a conventional spray paint stencil.
I printed mine on my old Lulzbot AO-100, because of its removable print bed. Printed in PLA, and then threw the bed in the freezer for a few minutes to pop the part off without damaging the bridges.
For best results, use a spray adhesive to hold the stencil to the surface you're enhancing, and add some masking tape around the perimeter. Work quickly so that the spray adhesive doesn't dry before you're done.
