Creality CR-6 40mm Fan Adapter Plate

thingiverse

This is a model I built to attach a 40mm fan to the stock CR-6 heat block. It fits perfectly in the stock fan enclosure and the grill on the front almost looks like it was designed for a larger fan. It loads upside down, so be sure to flip it over in the slicer. I chamfered the bolt holes in the middle so that they can bridge up to the bolt diameter, but you may have to clear out some loose filament in them. You will need a bit of hardware if you are going to print this. I recommend a M3 hex socket head with button type or knurled type screws that includes nuts for the bolts. The kit I purchased when I bought the fans was a M3-M5 kit.
