Trainman2001 posted:I redrew the valve covers and put a lip on the open one to give it some gluing surface. I'm going to print the open one as a separate object. The heads will also be a separate print. I mentioned this before that I'm going to treat this almost as a model with separate pieces helping to reduce the print failure potential.
So, this raises the question of the feasibility of printing functioning components. With the resolution of these devices, one can start to think of printing working gear chains, crankshafts, rods and cylinders that move, etc. I wonder how small a nut and bolt you could print that would screw together?
Some day, I guess we will be printing working locomotive drive gear.
