Rostock Max V2 E3D V6 Ultimate layer fan shroud by HJ3D

Last crawled date: 3 years ago

This cooling rig dramatically increased my print quality. I can now print overhangs over 45 degrees cleanly and consistently.
As you can see in the CFD simulation, the 3 air ducts channel the air exactly down the center. This maximizes the cooling of the printed section. This effect can clearly be felt on the actual printer.
Installing the E3D V6 on the Rostock max is easy, but thanks to its compact design it's hard to fit a layer fan. I've tried about 10 different shroud designs, fans etcetera and found that either they didn't fit, or they would not blow in the right direction. Finally decided to design my own cooling rig.
I've edited the layerfan shroud design by dreyfusduke to fit the E3D V6 with the effector plate either inverted or normal. It cools the prints instantly, but when using 3 50x10 radial fans the fan speed setting should not exceed 70% or nozzle temperature will drop dramatically.
You can now easily tune the cooling to your needs. Either remove all fans for maximum print speed, use just one for medium overhangs, or use three for maximum cooling for the most complicated prints.

-- Update --
With the original Rostock V2 U-joints, these shrouds need 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!
