The star of my E220 (build year 2009) was ripped off (by myself by accident :/ ), so I designed a substitute (first a nice little Chicken, see here: https://www.thingiverse.com/thing:2843353 and the attached pic of the chick).
A friend asked me if I could also do a boar for his Mercedes so I mixed up the walking boar by bs3 with my Mercedes Star Chicken Substitute. To get it into the right position I rigged the boar and did some minor adjustments.
I split it in half so it prints more sturdy. I recommend 3 or 4 perimeters. The two halfs need to be glued together. Spray-paint it chrome to make it nice and shiny ;)
It fits very snuggly on the cars hood and is held in place with a safety pin. The hole has to be drilled through the base pole first though (see picture).
