These are printable components for a vent system for Elegoo Saturn 4 Ultra printer. Although targeted for use with resin printer, the components are intended to be printed using filament printer. You can use PLA to print them.

As the vent cutout in Elegoo printers has the same dimensions (75mm diameter), it should also fit other Elegoo models in the series, although there could be limitations, especially as other printers have the backside as part of the removable lid, while Saturn 4 line has a tiltable lid and fixed back side.

One feature of this system is that the fan is positioned internally inside the printer. You can use either 80mm or 92mm computer fans, I include adapters for these two sizes. Unfortunately 120mm fan cannot fit inside.

Placing the fan inside the printer requires drilling a small hole in the back of the printer, just below the fan, to bring the power in for the fan.

Back side and the other components of this system include holes to fit in magnets of 6x2mm, which you can easily purchase from Amazon or Aliexpress. The spaces for the magnets are inside the prints, they require no glue, but they require to set a pause when printing on FDM printer, insert the magnets in the pause (pay attention to their orientation/polarization) and then continue printing.

I am lucky that my printer is just next to a wall behind which is my garage. So I can lead the stinky resin fumes into garage and keep my house without the smell, while keeping the printer in the room temperature. As the wall is wooden, I was quite easily able to cut the hole and lead the pipe there (unfortunately not in the same height, due to some installations, but very small distance below).

There are also parts for the wall. For the outing, there is even an option where you can mount another fan, this time 60mm. Actually I use this setup of two fans, one inside the printer (at the entry of the path) and another one at the outing on the other side of a wall (at the end of the path) and it works briliant. I bought 2 Noctua fans, both 5V version and power them directly from the printer USB port (with a power split)

Other material that you will need for this system:

• 48pcs 6x2mm magnets
• 4pcs M3x10 screws to hold the fan adapter and backplate (unfortunately the M3x6 screws from the printer are too short)
• 4pcs M3 nuts
• 4pcs 6#-32*30mm screws to hold the fan to the adapter
• 80mm diameter Aluminium Foil Ventilation Pipe (normally used for a kitchen hood)
• 2pcs 65-89mm diameter Worm Clips (to tighten the tube-connects to the alu pipe)

Printing wall-cover-lid.stl requires supports. Other components require no supports. I recommend using smooth plate and you may consider ironing top surfaces.
