This is an adapter for the Elegoo Centauri Carbon which mates to a 2.5inch ducting system. Other folks have covered 3 and 4inch mods but I needed 2.5 specifically. I prefer the 2.5inch ducting as it is a little easier to route than the typical 4inch stuff and has more than enough capacity. There is also the nicer looking hard clear tubing available if you wanted to construct something more aesthetically pleasing.
For printing stinky ABS/ASA parts you really want to have the exhaust from the printer case vent outside. And to print PLA with the case closed for noise reduction some active exhaust extraction may be necessary for chamber cooling.
This is oriented to emit vertically and plumb directly up the wall where it can feed into the air management system in my workshop. While I have an active system, you could use it as a simple passive system with 2.5inch ductwork and rely on the case fan pressure alone.
The exhaust duct attaches to the back of the machine via two existing panel screw locations. You will need to replace the existing M3x4mm screws with ideally M3x8, but there is a bit of wiggle room so perhaps 6mm or 10mm might be okay as well.
Printed from eSun PLA+ at 220C with 3wall, 15% gyroid infill, and tree supports.
Required hardware: 2 x M3x8mm screws
I didn't bother with a gasket as the chamber is pretty leaky anyway so seems like it would be overkill. It would be easy to make a TPU printable gasket or change the outlet orientation - let me know if there is interest in that and I can add some more models.
