Been playing with metal laser sintered 3D printers lately and wanted to create a stainless 240Z gearknob. Went through a number of iterations and ended up with this design. It's the same size and shape as the original 1970 240Z 4 speed one. Will be running the first metal prints next week, will be interesting to see how it turns out. 3 Z logos are engraved on the main part of the body, the original gearchange pattern is enlarged in size to print more cleanly than the original smaller one.

Will it actually print polygonally or will the exterior be smooth and consistent? Restated, will the exterior be multifaceted or is that just a graphics display issue?

@Patcon the exterior will print smooth, it's a graphics display issue and how SolidWorks saves the .stl file. When you slice it for printing the surface is rendered smoothly. Will post a picture of the first sample print when it's done, I'll do a trial piece in laser sintered nylon first. This is a sample off the Prusa 3D printer in SLA, much smoother than the graphic rendering. With laser sintering it uses powder to print the object so the layer lines and polygons are smoothed out. These are for my own use, I have no plans to sell them.
