I am assuming there are some out there. However, you may just want to become an Amazon.com affiliate as you would then be able to really choose a variety of different brands and companies. Also you may want to sign up for CJ.com and see what they may have in terms of affiliate offerings. The market for filament is just getting started so I don't think that many companies are even considering offering affiliates a cut yet. This will likely change though.
