AnkerMake M5 Direct Noctua A4 Extruder Fan Mount

An efficient ducting mount for a Noctua A4 Slim Fan on the extruder of your AnkerMake M5. Make your printer significantly more quiet.

No supports needed if printed in the orientation provided and no brims required. Use PETG/ABS/ASA/Nylon or anything that can stand up to a bit of heat. DO NOT use PLA or PLA+ as it will get melty and significantly deform.

You'll need a voltage regulator (buck converter) to step down the voltage. I used this one and designed my integrated mount around that, but any converter that can step down 24VDC at the to 12VDC at 0.25 amps will be fine. I attached a STEP file so you can modify the parts to suit your needs, feel free to post remixes! OnShape Link

Check out the optional Afterburner attachment here.

I've done a couple 6+ hour PETG (245° C nozzle, 80° C bed, 23-26° C ambient) with absolutely no issues even without the Afterburner. If you run into a clogged extruder due to heat creep, please let me know with the ambient temp, nozzle temp, bed temp, and your best guess on what time into the print the clog occurred.

IMPORTANT! READ BEFORE DOING THIS MOD: You will need a new part cooling solution for this mod as it will interfere with the default part cooling bracket. I chose to use this one (thanks Jared!) as is and designed the ducting to accommodate the extended version without modification.
