An assortment of badges I hand drew in Procreate/Inkscape/Fusion 360 to practice line work and because I didn't see any already on Printables.

The Hellcat, Demon, and Hellephant are about 1:1 scale with the real-world fender badges. The SRT badge is about the scale of the one on my rear spoiler.

The eyes on the solid versions are set about 0.2 mm higher than the background, so that you can add a color change without MMU if you so desire.

You can remove any back-plates I did by slicing it above the plates, and scaling it on the Z-Axis. You can also add your own back-plates in Prusaslicer by throwing some generic rectangles/cylinders/etc underneath.
