Anyone into 3D printed stuff for their car?

I agree with you too a point, but, you can print in metal (still $$$'s) or print in plastic and sand cast in metal. Haven't tried it yet, but, I have been eying it.

On your original point, yes, coming up with actually usable ideas is a bitch. Once my CNC is operational, I am going to be friggin dangerous
