Print Head Dual Fan Adapter v2 for Monoprice Select Mini

Allows two 30mm fans to be mounted to the print head of a MP Select Mini 3D printer. I built this in order to improve heat break and layer cooling, and to allow the layer cooling fan to be switched on and off independently for printing ABS.

UPDATES FOR V2: Added a lip at the top of the fan duct to stop it from sliding down the heat sink. Increased diameter of screw holes to accommodate #4 screws without modification.
