Here is my latest kick making TR stuff, these are pretty easy.
Can be any size these are about 4x4", I just take a white blank of corian or plexiglas and spray paint it black, from there it is simply a matter of etching the design then putting on a clear coat. Stuff like this CNC has an advantage over printers I think, laser I would think could do this.

Dunno, printer and laser are on my bucket list so I don't know a whole lot about either, I know a printer could spit out those grips pretty easily.

oh sheesh, here we go again, being told "File is too big (0.17 MB). Max size per file is 0.1678466796875 MB."
