Something that small can be 3D scanned and clean up.
The product I’ve used - optical scanning - and seen used - quite effectively - is this:
Low end scanners and software will not come close to good enough to make the effort worthwhile. Even with a high end scanner, the clean up is going to take some time. Multi-spectral scanning leads to the best results fastest.
Another approach is a “touch probe” - mechanical scanning - to generate a “point cloud” and an STL from that. Here is one example:
There are many others at various price points.
The optical scanning is likely to produce a better model and do so faster.
Inviting @WillAdams as I bet he knows of some good choices.
