I converted this excellent Dodge Charger model into a Polk County FL sheriff's car. No painting is required, all artwork is done as separate stls. To remove “Polk County” simply make it the same color as the body. The windows and tires can be printed separately to reduce the supports required and to limit color changes. Or, the whole model can be printed at once by dragging all the stl's onto the plate at once. I printed at 200% in PLA, 5% infill.
I have included a .3mf for Bambu Studio for my pre-configured settings, as well as all the stl's in folders.
