(Doesn't look exactly as depicted above)
I've lately made myself familiar with a service called
Shapeways, which, in a nutshell, prints your 3D model into a physical object.
I made this
DK Coin, which is available in two different gold platings and the default white plastic. It's 4 centimeters wide and high and 0,7 centimeters deep.
I've also made the K-O-N-G-letters but I haven't uploaded the models yet. You can check my
shop for all my models. I'm also working on the other coins throughout the DKC series.
The service is really awesome and I encourage everyone to join.
