Thanks djjerme! I haven't done anything with them yet, but will keep this in mind when I finally do.I’ve printed this same file as well, though scaled it down a bit for what I used them for. The person who built the file has multiple version of the hands and they were originally designed to hang on a wall. You can did the files on Thingaverse..
Depending on the material and layer thickness, I’d try to sand them first. Depending on the material used, I’d use a high build primer that’s plastic compatible to fill some of the surface defects and smooth them out. Then your top coat.
