I have recently acquired a 500 gallon air compressor, used in conjunction with a sandblaster large enough to fit a small office chair in. My hopes are to use this sandblaster, instead of the traditionally acetone and chloroform, to smooth some of my 3d printed parts, most notably the case and knobs. The face plate is going to be a rather difficult piece to 3d model, so i have thrown away hopes to print it, and instead make a mold of it. I have mentioned this before, i think, but i just feel that it fits into this post.

Hi McGee, I'm an avid 3d printer/modeler myself, and I'd be happy to help if I can! I only just joined the NBTV forum, so I'm still getting caught up on all the information contained here, but I think I have a grasp on the mechanical parts!

I'm wondering if the faceplate could be modelled as per lithophanes. Using brightness to represent height - there is lots of software around already to convert an intensity-coded image into a 3D height-mapped object.
