This combines the E3D V6 retainer clip with a 30mm fan mount for the E3D V6 fan mount.
Prints vertically without supports, if you have faith in your bed adhesion! (You could also print it horizontally, but the fit to the cylindrical surface of the hotend might be affected by the layer lines.)
Fusion 360 archive is provided.
2x M3 screws needed for holding the fan.
