I think you will find it hard to get a budget 3D scanner and 3D
printer to make acceptable knobs with any type of fine detail. Or fine
finishes for that matter. Some folks print stuff using ABS and then
polish the stuff in an acetone vapor chamber of some sort. That can
work pretty well. But still the best resolution of inexpensive
printers is ends up to be, in a practical sense, about .25mm, or .010"
at the finest. The cheapest 3D scanners that will scan stuff to a
resolution of .1mm, or .004" start at about 700 bucks.

I am looking for suggestions on a 3D printer & scanner - either as one piece of hardware, or two. My needs are both small and simple. Such things as knobs, handles and similar parts with no dimension longer than about 5" (130mm). I don't need speed, but I would appreciate accuracy and the ability to reproduce details such as knurling and scrolling on small parts.

I am somewhat price driven, but not to the level of absurdity. Nor am I any sort of adept with the software, never having done it before. So, simple-is-good.

Thanks in advance!
