I didnt read at 1st that you coudl send them designs. Probably all they do though is flat or slightly curved surfaces. Anything more detailed would cost allot more. They seem to be pretty good priced for prelaminated Carbon Fiber. It is going to be a bit thick from what i can see in the pics though. This stuff would be good for like dash overlays ect. Would deff work for a switch plate. Just need to reinforce the back. U woudl probably be albe to just buy a sheet from them and do it yourself. Get a box cutter, sharp scizors and prob a dremmel and you will be good to go.
Check out the few thingss i did with preepoxied carbon fiber in my profile. Did gas door, Heatshield, and licenseplate backing. Prettymuch becasue this stuff is so reidged with precoated c/f, ur limited to pretty smooth surfaces. IF you have any other quesitons let me know.
