>>8754820You mean WFC-compatible effect parts? Shockwave Labs just started making LED blast effects, and that's pretty much it. Blast effects require the use of rubbery soft-pvc and 3D-print accessory makers don't seem to have materials like that. For SL's effects, they taper 3mm hole/5mm peg slightly so it'll fit snug on the WFC ports/pegs, but the fit is still not as good as the rubbery, grippy official ones.
