Not my car, exactly, but finally finished off these replica DSV and Proto-1 grille emblems:
The DSV is laser-cut, the DMC is 3D printed. Both are mounted to a flat base with rounded edges as per the Bill Collins car grilles, and both have a brushed-metal effect paint job.
Here's an image of the DSV logo on the epo-wood mockup.
I seem to recall seeing a photo of the epo-wood car with the "JZD" emblem on it, can anyone confirm that? If so, then I've still got 3 more to make to have the complete 'set".
