Wanhao Duplicator 4X Cooling Fan Duct

thingiverse

Having found no fitting models for my printer, I opted to design a new one, combining ideas from various designs such as <http://www.thingiverse.com/thing:259688> and <http://www.thingiverse.com/thing:221306>. It is specifically adapted for Wanhao Duplicator 4X. The height can be adjusted to match your nozzle height exactly. Remember to break the small supporting part on the front. Feel free to improve upon this design. This model has undergone several updates, including adding an inside reinforcement to Rear Fan v4.5 (<em>UPDATE 11/5/2014</em>) and a Rear Fan for better results (<em>UPDATE 5/4/2014</em>). The Rear Fan can be fixed to the replacement cover. In <em>UPDATE 18/5/2014</em>, Rear Fan v3.3 with clips was added for greater robustness and resistance to vibrations. You'll need 2x M3 nuts and 2 * M3 10mm screws for attaching the clips. An alternate version for Front and Rear (v4-4) was introduced in <em>UPDATE 25/7/2014</em>, which also includes a Y axis switch stopper to prevent issues with the back. Finally, <em>UPDATE 08/01/2015</em> features a photo explaining how to install v4-4 (the same system applies for Front and Rear). Just print and remove the small supporting part on the front, and use 2xM3 60mm cap screws hex head.
