Instant improvement in print quality. Used a Sinwinn 4010 24V fan from Amazon.
Printed in PETG @0.2mm 100% infill 230 temp on a CR-10. Seems to be holding up to PLA printing fine so far (will likely reprint in ABS or Nylon for hotter future prints).
Mounted on a Qidi Tech 1 Dual Extruder (basically a FF Creator Pro) with zero problems mounting.
