Frankly, a few dozen passes with 120-220 grit, (with the grain) followed by a quick acetone wipe down (picks up any particulate) and then a couple light coats of gloss varnish (spray; 8-10" away, just enough to begin saturating the surface) varnish before waiting 24hrs+ (ie. gas off) to box it up… is the pro move here. 🫶🏼🤓
Or just do it in the garage. Not to devalue your point (because you aren’t wrong either, the dust isn’t probably healthy), but honestly thinking back over all the shady things that have gone down in my garage over the years, sanding a bit of PLA wouldn’t even nick the surface.

I try and avoid sanding plastic as much as possible even if it’s PLA
Just do it outside then.

Lmao I recently spilled a liter of hydrochloric acid in my garage.
I get that but creating microplastics to get a smooth finish on an Xbox controller faceplate doesn’t seem like a good move to me.
I’ve never tried it but this method looks interesting. I wonder if it would work with clear primer instead of paint.
