Rostock Max V2 E3D V6 Ultimate layer fan shroud

thingiverse

This cooling rig dramatically boosts my print quality. I can now print overhangs over 45 degrees cleanly and consistently without fail. As seen in the CFD simulation, three air ducts channel the air precisely down the center, maximizing the cooling of the printed section. This effect is clearly felt on the actual printer. Installing the E3D V6 on the Rostock Max is easy, but its compact design makes it hard to fit a layer fan. I've tried about 10 different shroud designs and fans with no success - they either didn't fit or wouldn't blow in the right direction. Finally, I decided to design my own cooling rig. I edited the layerfan shroud design by dreyfusduke to fit the E3D V6 with the effector plate either inverted or normal. It cools prints instantly, but when using three 50x10 radial fans, the fan speed setting should not exceed 70% or nozzle temperature will drop dramatically. You can now easily tune cooling to your needs - remove all fans for maximum print speed, use just one for medium overhangs, or use three for maximum cooling on the most complicated prints. The original part by dreyfusduke is located at http://www.thingiverse.com/thing:614597. -- Update -- With the original Rostock V2 U-joints, these shrouds require some sanding/cutting to create enough clearance with the U-joints. I now have the new SeeMeCNC ball-joint upgrade with the new effector plate, and these shrouds still work great with the new design!
