This is the improved design of my vent that I originally designed for 3D printer enclosures. It has an optional grille on the outside and inside. By printing the vent with grilles on both sides, you can put a filter into it.
The vent uses a rotation lock for installation and stays safe in place.
How to Print the Vent
I prepared PrusaSlicer projects where all required settings for the print are made. If you like to slice the models from scratch, check out the following table:
| Nozzle Size: | Recommended 0.4mm, works with 0.6 and 0.8mm The grille may cause problems with a 0.6mm nozzle. |
| Layer Height: | The model was designed for a 0.2mm layer height. |
| Filament Materials: | Recommended PETG, prints fine with PLA |
| Perimeters: | Three perimeters |
| Prusa Slicer Profile: | “0.2mm Quality” |
You must print a matching pair of LR2305-E… and LR2305-I… models that share the same diameter value.
Dimensions

The filenames of the model files look like this:
LR2305-E-G<grille>-H<height>-D<diameter>.3mf
LR2305-I-G<grille>-D<diameter>.3mf
External and Inner Part (E, I)
The letters E and I after the project number specify if the model is the external or internal part of the vent. E stands for external (outer) and I stands for internal.
Grille (G)
The character after the letter G represents the type of grille the model has. This project has two variants: h stands for a hexagonal grille, and 0 stands for no grille.
Height (H)
The number after the letter H specifies the thickness of the wall in which the vent is installed. The number is in millimetres.
Diameter (D)
The number after the letter D specifies the hole's diameter in the case where the vent is installed. The number is in millimetres.

Photos
The vent in the photo are the models LR2305-E-Gh-H10-D030 and LR2305-I-G0-D030. They were printed on an Original Prusa i3 MK3S+ using Prusament PETG Signal White.
Conclusion
This improved vent design should be easier to install and works well with PLA. If you found it useful, please rate it and upload photos of how you used it.
Happy Printing!
