This is not an entirely serious design: a 12V radial fan of that size generates about 20 cfm of airflow without the filter in place, so realistically this will not improve air quality in a normal sized room in a reasonable amount of time.
It will filter air though, so if you place this in a printer enclosure, or near a particle source, it might help. Or if you really just want a very, very clean fresh breeze of air in your face, or need to pipe N95-filtered air somewhere - the radial fan is easy to hook up to some tubing.
It's 2020, please don't use new N95 masks for this. I sacrificed a 'used up' one that became uncomfortable for normal wear after long-term use.
The practical aspects of the design: it's a straightforward print that should clip into place on a DC-PR-3 12V fan. The filter self-seals with the negative pressure from the fan, but a bit of hot glue helps.
