Important! this duct prints to 96mm high and when finished moves up to 98mm make sure your printer can print that high. Solid mount part cooling duct for Duinotech TL4076 requires 12v 60mm fan. make sure you use very small screws on the mounts as the linear bearings are behind the screw drill holes, also all the pilot holes on the duct should be pre-drilled. note the TL4076 default driver board has no part cooling fan connection points so you could just connect it to 12v. If you want to go all out as i did, you could update your motherboard to arduino + ramps 1.4. which will give you connections for a heated bed and part cooling fan with speed control.
