Duinotech TL4076 part cooling duct. requires a 12v 60 fan

Important: This duct prints to a height of 96mm high and upon completion, it will elevate up to 98mm. Ensure that your printer is capable of printing at such a high level. A solid mount part cooling duct for the Duinotech TL4076 demands a 12v, 60mm fan. Make certain you utilize very small screws on the mounts since the linear bearings are situated behind the screw drill holes. Also, all pilot holes on the duct should be pre-drilled. Note that the TL4076 default driver board lacks part cooling fan connection points, so you can simply connect it to a 12v source. If you wish to go all out as I did, you could upgrade your motherboard to an Arduino + Ramps 1.4 setup, which will provide connections for a heated bed and part cooling fan with speed control. Here are the necessary parts: Arduino Mega2560 board Ramps 1.4 Controller Shield Board 4x A4988 Stepper Motor Driver Module Ramps 1.4 Controller Shield Board Adapter for LCD2004 A 15A power supply, as a 10A unit would run hot.
