Hello stranger! 
Regarding the FEP: Elegoo will send you a free set if you become a Facebook follower. Since I’m not on Facebook I asked if I could follow on Twitter instead and they said Sure. And sent me the link for the free FEP.
Also re: strainer cones—
I found that I was likely going to quickly run out of those so I just doubled up a couple layers of tulle ribbon from the craft store and lined a plastic funnel with it. Worked great to strain the resin.
