This is a pretty interesting idea by Thingiverse user “petrex”:
It’s a use of carbon fiber in an RC application which is good–especially for a person who is new to carbon. For myself, being that carbon fiber is my business, if I started to use carbon instead of 3D printing then I mine as well just use carbon, but making things that are made of filament is just cool! Using 3D filaments intrigues me and so, for me, I’m sticking with the filaments.
