YAAA3FD - Yet Another Aurora A3 Fan Duct

thingiverse

Update: v13.1 is a lower profile to better fit under the X-Axis carriage mount as some users have experienced issues with the original design. This is yet another design for the Aurora A3 Nozzle Fan Duct. Instead of a doughnut shape, I'm trying a dual ducted approach to try to get more air to the back of the nozzle. This should help with overhangs on the back side of models. It also allows easier access and viewing of the nozzle/hot-end itself. I've been testing it for a few months now and pretty happy with the results. It's a friction fit into the cooling fan outlet, so it's very snug. But that helps keep the back-end from sagging. You will likely get some warping of the plastic (if using PLA) around the side as its fairly close to the hot-end. But I've not seen any delamination from this. Having an insulated hot-end helps. Give it a try, see if it works well for you. No warranty expressed or implied. Your mileage may vary. Contents may have settled during shipping and handling. Print Settings Printer: JG Aurora A3 Prusa I3 Rafts: No Supports: Yes Resolution: .1mm Infill: 100% Notes: Must use supports (I hate supports), but 'Touching Build-plate' only. The sides are only .5mm thick for minimum weight and the top/bottoms are very thin as well. So 100% really doesn't matter. It's all single wall anyway. I printed this at .1mm for increased layers (especially on the top, bottom and slopes) for better strength (I believe). If you're printing with a nozzle larger than .4mm, it may not slice/print because the walls are so thin.
