Hot End Cooling Duct & Part Cooling Duct

thingiverse

These are cooling ducts for a Tronxy XS5A Pro with a Micro Swiss all metal hot end using the stock 40mm hot end cooling fan and part cooling fan. All parts are designed to be printed without support. There are three parts to be printed for the hot end cooling duct: the main duct body, the fan intake, and the fan exit. It is designed to efficiently flow air across the heat sink and then exhaust out to the sides. One side of the duct has mounts for the auto leveler and the other side has a mount for the part cooling duct. The part cooling duct is 2 pieces and the lower part can be removed with 1 screw to ease in maintenance, cleaning, nozzle changes, etc. This is my first design to be uploaded to Thingiverse, so any feedback is appreciated and I would be happy to share the CAD files or modify the design to make it better. Feb. 10, 2020 Update: Lower Part Cooling Duct (Mk II) modified to reduce the bridging distance which also added channels that should help direct airflow equally to the four nozzles. Feb. 10, 2020 Update 2: Lower Part Cooling Duct (Mk III) enlarged exhaust ports to improve airflow to part. Feb. 13, 2020 Update: Added part files and a couple of assembly files from Fusion 360.
