Bondtech BMG and E3D V6 Direct Fanduct

thingiverse

I was really looking for a top-notch fan duct to pair perfectly with the Bondtech BMG setup on my CR-3D C1. I came across this fantastic fanduct that would fit seamlessly onto any setup featuring an E3D V6 and Bondtech BMG Extruder, including the upcoming Volcano Version which I'm excited to test out. My main objectives for the fanduct were: 1. Easy removal of the fanduct in case any adjustments needed to be made to the hotend. 2. A 40mm fan for efficient coldend cooling. 3. Effective 360-degree cooling utilizing two 4010 blower fans. 4. As compact a design as possible. 5. A mostly enclosed nozzle and heater block when installed, keeping fingers safely away. I believe I've successfully achieved these goals and I'm eager to hear your feedback on the design or any improvements you'd like to make by remixing it with your own ideas. Due to the close proximity of the heater block and the fan duct, it's essential to print the fanduct using a temperature-resistant material such as ABS or ASA. Additionally, use a silicone sock for optimal results. If you plan to mount the fanduct flush against a surface, as shown in the Fusion 360 image, make sure to use a high-static-pressure fan like the Noctua 4020 which worked flawlessly in my open printer setup. However, with an enclosed printer, it's best to opt for a more powerful 24v fan.
