This is a replacement nameplate for the front grill of a 2006 Chrysler minivan. Use the blank design and add your own logo, letter, etc through Tinkercad or other similar software. It's a 67mm x 43mm ellipse with a height of 7mm.
Pry off the grill piece from your vehicle. Remove the existing nameplate (it is held on by adhesive). Print your new piece and secure using a M3 x 8mm screw. Adhesive can be used of course, but I like using a screw in case I want to change it.
Part prints good in PLA. About 25 minutes on my printer.
