I Ordered Up Two Sheets of Carbon Fiber Composite

3/8" and 1/8" thick. I do not know why the 1/8" came out so pretty but if this is an option that I stumbled on, I will do it again.

UPDATE: There is a gloss finish option that is only slightly more expensive    i will use this for all subsequent parts, although at this point, I may already have all the stock I need.  There is a glossy veneer available that has an adhesive backing.  I might buy some and cut to fit existing parts that I have cut. That 1/8" thick sheet is strong and stiff in a way that shames carbon steel.  There are many parts that I originally intended to be 3/8" but now seem like 1/8" or even 1/16" will do fine: parts that have no real load.
