That came out nice. It captured a lot of detail.
I don't mean to be such a critic, I'm just trying to help out.
I'm a big nerd when it comes to 3D modeling and I spent hours figuring out the whole 3d scanning thing.
Scans are usually used for reference only. You can fill in the holes of your scan and print but the quality wont be the best.
Usually you import the scan in your preferred CAD program and align the part with your coordinate system. I try to align and sketch on the flattest surface on the part. Once that is done, all you do is trace the scanned part and extrude/ revolve your sketches.
This video helped me out a lot.
