I like the look of silicone parts made from sandblasted aluminum molds. Up to this point, I have been performing mostly 2.5D CNC work; it is now time to try out 3D milling ("surfacing" operations), in order to create more interesting shapes without relying on 3D printed molds.
A part to start with 3D milling (also trying out the Creo renderer...):
First time using "surfacing" on MasterCam:
Result (shown with some dowel pins):
The result. The finish is quite good -- looks almost like something that one might buy at a store (cheaply):
