My 2nd attempt using Blender, this time I was able to integrate Luxrender 1.6.0 as an addon, so now I can render images using a lot more fancy materials and controls :) This is draft V 01.0C for the 3D printed Raman Probe assembly, and I also included a platform I built custom made just for this probe.

A little "dirty" in some spots but that's only because I'm still learning how to use the program :)
