Two things prompted me to make yet another v6 mount and layer fan:
1) The lack of a compact efficient layer fan for delta printers. Which I needed since I have an enclosure on my RMv2
2) My old bulky layer fan was absolutely abismal. It would get caught on prints and wreck hours of prints, and and didnt even cool all that well.

I pulled inspiration from the Atom 2.0 Delta printer, google it! Quite fancy delta printer!

This layer fan is the second attempt, my first design had issues with the air stream being too far from the nozzle. Which meant that the PLA would just look like poop.

These are the fans the holder is designed around:

Too get an effective layer fan I had to pull in the air stream very close to the nozzle to get the results I wanted. On the first few layers when the fan turns on, it will lower the temps maybe 3 degrees. It shouldnt be any more and it doesnt cause any jamming. As you get farther from the build plate the temps normal out. I have 60 hours of testing and printing with this setup (w/ long 15 hour prints) You must make sure the fans are seated correctly in the holders.

The collar and ring for mounting the v6 are pretty standard and straight forward. The notches are to keep your wires close and through the effector.

1) Flip effector - smooth side facing bed
2) Put all wiring through effector hole before mounting
3) Seat fans in holder - NEED to be fully seated. Use vice grip to push fan in to holder. The fans are metal, dont need to worry about being gentle
4) Place ring and collar mount on v6 - Collar opening facing toward z arm (backwards)
5) Hook up all wiring if you havent already done so.
6) Re-calibrate bed level with new nozzle height
7) In your slicer set min fan speed to 35% and max to 100%

I printed in ABS, because I needed/didnt have a layer fan for PLA.
Should be able to print in PLA without issue, the mount and layer fan holder arent touching or near any hot zones.

Connect the laptop fans in parallel to a single 12v fan line on your printer.

Thanks for this! I too really like the Atom but can't afford it :( I've been searching for the fan they use but haven't been coming up with anything until now. Do you know if the panasonic fans are the same Atom 3D uses? Would you have the STEP files for the fans?

Sorry just saw this! From my understanding they are very similar. I believe the Atom outsources their own fans. But the specs are similar, and even so I've gone through several designs to make this the most efficient for the RMv2 + E3Dv6 Combo. If you look at the Atom, the angle at which their fans sit is incredibly steep and works with their certain hotend which is proprietary. If I can help in any other way please let me know!


Doesn't this reduce your printer's height by the entire height of the hot end?

Could this work on a delta that isn't a Rostock Max? I ask this because I wan't this on my HE3D delta.

Ok hot shot - now put a 90 bend in that bridge :-)

Seriously though, I'm actually very impressed! That is probably some of the best bridging I've seen. Laptop cooling fans are nice and light too - great idea.

As much as I would love to take credit for that video, that is actually the Atom 2.0, which is what my layer fan is designed off of. I havent tried anything like that yet, but I guess Im always up for a challenge!
