Round vent cover (FreeCAD, parametric, Lüftungsgitter)

Round vent cover

There are some good OpenSCAD files available but they did not have what I needed. Especially no holes for mounting. So I made this in FreeCAD.

If you need a specific size and you're not into FreeCAD that much, let me know!

Modify the FreeCAD file as you like. Just double click on the table (last entry in the feature tree) and edit away.

If you don't like the mounting holes or the chamfer (or the support for the slats!) just right-click the feature and hit “suppress”.

Is this thing useful to you?

Don't hesitate to hit the ❤ and show some love. I'm always happy to hear from you in the 🗩 comment section. If you have problems printing my files: tell me in the comment section too!

Provided files

I do like to have real CAD-files, when downloading things from others. Most users don't provide files other than .STL-files. These are useless for further manipulation or quick changes. So I'll provide the following files to you:

Updates

• 2024-07-26: Added variants from 30 to 100mm tube diameter in 10mm increments
• 2024-07-14: V0 uploaded

Is it easy to build/assemble?

No assembly required. The thread already has +0.2mm clearance, so it should work just fine. A calibrated printer is needed anyway!

Is this thing finished?

yes
