<p>I've been reading and experimenting with Acetone vapour smoothing on some printed ABS parts.

I've been reading and experimenting with Acetone vapour smoothing on some printed ABS parts. My problem is that I need to selectively smoothen the printed parts which vapor smoothing doesn't allow. In particular, the cogs, whose sides I was trying to make smooth ended, up with smooth rounded tips, which was a disappointment.

So how can I maintain fine details (like the cog tips in the image above) while applying smoothing methods to printed parts?
