A part cooling fan mount for Chimera style dual hot end with integrated 30 to 40mm hotend fan adapter (mostly used to mount Noctua fans).
Fits any Chimera style dual hotend where heater blocks are turned so that heater cartridge and thermistor wires are perpendicular to the X axis.
Full assembly requires:
2x 5015 blower fans
8x M3 screws
4x M3 nuts
For chinese clones, you'll need to sand down the bottom of the duct by a little bit. 10 minutes of sanding should do.
Use supports if you don't have an efficient part cooling fan.
Print tested with PETG: 12h print with 220 nozzle temperature didn't distort the mount.
