Ender 3/Ender 3 Pro Cooling Duct
cults3d
UPDATE: This is version 2. It has been updated. The holes are now in better positions, small fixes (tighter tolerances), and aesthetic updates. The largest difference is a change to the air blower. I went smaller but used a directional blower for the air. I found that the other blower, in certain circumstances, would sometimes get caught on the print. This solves that problem. This is a cooling duct system for the Creality Ender3. The purpose was to replace the stock fan with a 40x20mm fan instead. I wanted to get close to the print head but only put air on the part, not the nozzle.For that purpose I used the nozzle portion of the following air duct that was made for the stock fan (https://www.thingiverse.com/thing:3255518). The channel in the side was designed that way to miss the bolts that are apart of the belt tensioner. Please make sure to print this in PETG or ABS to reduce the risk of melting. You may use this design for anything you wish, so long as credit is given to myself and the other author. The only other stipulation is that you give it away for free. That means that no part of the design may be used to make a profit off of, nor even to cover any costs you may accrue. As always, make sure this works for you before you try to use it. As I take no responsibility for your usage of this design, I would not want any damage to happen to your printer or someone else's. The responsibility to make sure this works for you is up to you.
