ProMega compound fan shroud - 40mm fans
thingiverse
I customized Ktappers design to fit my printing needs. It relocates the airflow from the part coolers closer to the nozzle, resulting in improved prints for me. I incorporated a slot where the wiring for the extruder fan can run and be secured with zip ties. A silicone sock on the heat block might be necessary; I've already got one and haven't encountered any issues. Without it, your heatblock may cool down during printing or remain perfectly fine. This version is optimized for a 40x40x10 front fan and a heatsink assembly. The heatsink used in this design can be found at https://www.amazon.com/gp/product/B07CSPKF8Y/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1. Multiple fans were utilized: - The extruder fan is available at https://www.digikey.ca/product-detail/en/sunon-fans/MF40100V1-1000U-A99/259-1794-ND/6198732. - Cooling fans are available at https://www.digikey.ca/product-detail/en/delta-electronics/BFB0405HHA-AF00/603-1562-ND/2560685.
