E3D clone Cooling Fan and double Part Blower

thingiverse

I've tweaked xile6's original 30mm print cooling fan design with a second cooling fan installed directly next to the hotend nozzle. As originally envisioned, the side ducts remain carefully offset from the nozzle to ensure efficient heat dissipation - you can see my modified OpenSCAD file for further clarification.NOTE: this particular mod is specifically tailored for the cost-effective E3D hotend clone, which boasts a substantial 25mm diameter heatsink!\nDesign Breakdown\nThis object has been crafted through manual editing of the STL source file, which might raise some issues with certain slicers due to potential manifold or watertight integrity concerns. Luckily, I didn't encounter any problems while slicing it using both Cura and Slic3r without incident.
