Is he using PLA or ABS in the printer? If it's ABS then you can sand it smooth and put it in a Acetone vapor and it will smooth it out real slick. Lots of information on Acetone vapor treatment on the internet, but I don't think it works with PLA. I've got a few different containers that I use for the vapor treatment. One gallon steel paint cans work great for smaller parts.
