Reverse Smooth-ish Fang Duct for Ender3/CR-10 with Micro Swiss Direct Drive

thingiverse

This is a re-design of amass3d's popular "Smooth Fang" part cooler duct. The fan mount is reversed compared to the original in order to clear the Micro Swiss direct drive extruder. A modified version of frankybuilds' bracket was used, which required some tweaking to work with the Micro Swiss hot end. Frankybuilds' bracket can be found on Thingiverse at https://www.thingiverse.com/thing:3419869, and includes additional parts needed for bed leveling. The Micro Swiss extruder and hot end kit can be purchased at https://store.micro-swiss.com/products/micro-swiss-direct-drive-extruder. I'm not skilled at modifying meshes, so a new design from scratch was created. Although it's not as lightweight or aesthetically pleasing as the original, it gets the job done after several hours of work. Checking Thingiverse revealed that this design is somewhat redundant, but it still performs well. This part cooler duct was printed before switching to the Micro Swiss direct drive setup, resulting in some underextruded layers. However, tension issues with the extruder drive are now resolved thanks to the excellent Micro Swiss design.
