Fan mount for when you want to hang a 40x40mm off another 40x40mm at a 30 degree angle. I use it for an E3D on a MakerGear M2. However, even if I had the stock PEEK extruder, I think cooling the stem will reduce jamming - especially with PLA.
This system keeps the direct vibrations off the E3D.
If you have 24v like the newer MakerGears, I suggest these fans:
DC Fan Ball Bearing 24V 0.12A 2.88W 11000RPM 14.83CFM 41.5dB
Arrow.com has the best price.
You should bypass your case fan and then run the top two in parallel from E1-Fan and the bottom one on E0-Fan.

Print this with the large cutout on your bed and you do not need support.
