Installation Notes:

• Be sure to check the polarity on the wires you are connecting our fans to. Typically red is positive and black is negative but some of the Chinese printers do not adhere to these standards.
  • There is no list of what machines use what as it can vary from model to model and we have even seen differences in wiring colors used in the same printer models.
• Our fans use red for positive and black for negative. You can verify polarity with a cheap $10 multimeter from Amazon or you local hardware store.
  • If fans are shorted out/killed due to improper wiring this is NOT covered under warranty.
• When replacing a fan you will want to splice into the existing wire to your existing fan. Connect the wires with solder and heatshrink OR use our Quick Solder connectors.
• Some Creality machines have been reported to have larger size metal screw standoffs.

Part Fitment/Installation

This is a universal 3D printer part. That means it will work on almost any 3D printer (check your printer voltage and part voltage) with the correct mount for your specific machine. Thingiverse is a wonderful place to locate mounts and we also have printed parts in our shop for some universal parts.

It is up to you to determine and select a mount for your specific printer model (or design one) to install this part on your machine and wire it up to your machine (if applicable).
