Smoke Filter for soldering

This is a simple smoke filter for soldering. In the picture, you can see the filter(120x120x10mm) in red, the fan(120x120x25.5mm) in carbon black and the parts for 3D printing in neutral grey. If you have the listed parts, you are ready to 3D print your own smoke filter and get better experiences in soldering.

Parts list:

Fan(120x120x25.5mm)
Carbon filter(120x120x10)(Design with 2 filters will come up soon)
Threaded rod(4x)
Nuts(8x)
Prefilter(120x120)(narrower as 2mm, maybe from a vacuum cleaner filter)

If you have questions or improvements just put them in the comments.
