YAAA3FD - Yet Another Aurora A3 Fan Duct

thingiverse

Update: v13.1 is now a more compact design that fits seamlessly under the X-Axis carriage mount, resolving issues some users faced with the original design. This latest iteration of the Aurora A3 Nozzle Fan Duct takes a fresh approach by incorporating dual ducts to channel more air directly to the back of the nozzle. This enhancement addresses overhangs on model sides and provides easier access for viewing the nozzle/hot-end. After rigorous testing, I'm pleased with the results. A friction fit into the cooling fan outlet ensures a snug connection, preventing sagging at the back end. Be aware that PLA users may experience slight warping around the duct's sides due to its proximity to the hot-end; however, insulated hot-ends mitigate delamination issues. Give this design a try and assess its performance for yourself. Please note that no warranty is provided, and results may vary. Contents may shift during shipping or handling.
