35mm replacement fan blade Hobbywing Max6 / Arrma

35mm replacement fan blade for Hobbywing Max6 and Arrma 35mm fans

I made this a complete replacement vs a slide on design because I wanted the maximum amount of blade. A few millimeters matter when you need maximum cooling for something like the Max6 that gets pretty hot when in use.

Updated the clip design. It printed well and worked just fine printed at .15 layer height with a .4 nozzle.

8/11/21 Update: So... the screw version works best with a button head screw. You could screw in form the top of the fan blade, but it actually works best if you screw it in from the bottom though the stator. This secures the fan and at the same time is the shaft, just make sure there is some slop.

Instructions:

1. Remove sticker on the bottom of the fan.
Carefully remove the very small plastic retaining clip from the blade shaft. Pull the fan blade off the housing. Carefully remove the round magnet from the broken fan blade. Break away the shaft from the the broken fan blade and clean off any plastic adhered to it. Push the magnet into the new fan blade. (Optional but recommended: Heat up the end of the shaft that goes into the center of the fan blade) Carefully set the shaft into the center of the replacement blade. Its a very tight fit so taping it into place might be necessary, this is why I recommend heating the shaft up so it goes in easy and melts the material and securely sets it in place. I've noticed the shaft cools off very quickly so getting it really hot with a jet style torch helps. This is the most difficult part because it needs to be in the center and set in as straight as possible. Put fan blade back on, push the clip back on the shaft.
