E3D V6 (Clone) cooling fan - Compatible with Monoprice Select Mini V2

thingiverse

**Note the orientation of the blue fan duct in the images as this design is centered around this orientation.** This fan duct is compatible with an E3D V6 clone hotend, and its measurements appear to match those of the genuine E3D V6, suggesting it will also be compatible with the genuine hotend. The fan duct is designed for use with the Monoprice Select mini V2. It utilizes the MPSM's original 30mm fan as the part cooling fan, and a single 30mm fan as the hotend cooling fan, powered by a 12v power supply. Alternatively, the power wires within the base of the MPSM can be cut and spliced to power the hotend-cooling fan directly with 12v whenever the 3D printer is turned on. This design requires: 1 x M3x20 machine screw (socket head, button head, or pan head screws will work) Hex key compatible with your M3 machine screw 1 x M3 hex nut (A small pair of needle nose pliers is recommended to hold this nut while the screw is tightened) Soldering iron Solder Recommended: 1 x small switch (to control when the hotend-cooling fan is turned on/off) Optional: 1 x 12v DC power supply Optional: 1 x 2-pin male dupont connector (or similar 2.54mm/0.1" 2-pin male connector) to connect the hotend-cooling fan to the 12v wires The fan mount used is the "Aperture" fan grill cover by mightnozzle, available on Thingiverse: https://www.thingiverse.com/thing:2802474. Minor variations in the design include an open version without the Aperture grill and a "Low Profile" version that only mounts to the bottom two screws on the hotend-cooling fan.
