E3DV6 40x40x20 Cooling Fans

pinshape

I ordered a bunch of these 40x40x20 blower fans to use as cooling fans on my Tevo and thought, "just use them for everything!!" The photos included are printed with PLA and no cooling fan, as it hadn't been printed yet. If you intend to print ABS long term, I'd probably knock one up in ABS. Unscrew the standard 30x30 fan from the E3D shroud and screw this mount straight on! Mount the center fan first; the standoffs are for the right-hand fan because it needs to be mounted upside down relative to the other two. No supports needed. A couple of sneaky internal fillets and chamfers let the printer build up the internal ducting. The air outlet is angled down towards the nozzle internally, so don't stress about it not having a "nozzle." No supports are required. Print with the air outlet facing down onto the build plate at .2 resolution and 25% - 100% infill.
