I don't have a 3-D printer, but maybe some other forum members do own one and have experience using one. Would it be possible to take a nice set of 'Coke' grips, and duplicate them on a 3-D printer using some dark brown plastic media? Of course you would have to re-work the estuchion areas to fit some real ones from scrapped grips. I have seen some items that were re-produced on these printers and they look pretty darn close to the originals. Just a crazy thought.
