Tevo Little Monster 30mm hot-end fan replacement with a 40mm one

thingiverse

This is a fan-duct add-on designed specifically for the Tevo Little Monster, replacing the standard 30mm hot-end fan with a quieter 40mm blower-style model. The innovative blower style mount produces the quietest 3D printing experience I've ever had, although it's worth noting that reducing the voltage from 24v to 14v was necessary to achieve optimal results. It's also important to remember that blower fans have linear airflow, which allows them to outperform axial-style fans even at low speeds. <b>Update: Bolt Hole Mount Modification</b> The bolt hole mount design has been improved to ensure easy measurement and adjustment for different fan sizes. <b>Update: Modified Blower Style Hot-End Design</b> A reinforced fan mount has been added to the blower style hot-end, providing additional stability and support. <b>Update: Addition of Blower Style Hot-End Cooler</b> A new blower style hot-end cooler has been integrated into the design, offering an extremely quiet operation mode. <b>Update: 50mm Adapter Added</b> A 50mm adapter has been included to enable even more aggressive cooling levels. The add-on was created using OpenSCAD, and STL files are available for download. Initial testing with ABS material yielded no clogs or issues, indicating that the design effectively cools the hot-end. https://www.youtube.com/watch?v=aAFTFTt5R9A
