I looked into it, but it covers a different use case. It’s based on photogrammetry. For reverse engineering, you always need at least one measurement to scale the mesh. Also, you cannot scan anything bigger than the enclosed space within the scanner.

The einstar actually measures depth, so I can get measurements even if I scan the object from just one side. It stitches the measured points together by overlapping features, so it theoretically can scan infinitely large objects.

A big reason why I wanted an All-in-one 3D scanner was because I want to reverse engineer objects I see “in the wild” and in museums. The staff there might not appreciate it when I put a ruler on their stuff.

Yes, and even the bridge is amaranth!

Those are standard (albeit fancy) “french eye” tuning pegs from Thomann Germany. The endpin is in the same style. Maybe for the next instrument I will try to make them myself.

That’s probably because they’re closely related. Every region in Europe has their own variation of a small, pear-shaped, three-stringed instrument. There’s the Russian gudok, Bulgarian gadulka, Spanish rabel, and so on…

Nice! Please also join us on c/luthier if you like, the community needs a bit more activity.

You didn’t state your budget and requirements. GPD Pocket, maybe?

I want to make tailpieces (the part that connects the strings to the body) with decorative carvings for string instruments like violins. This piece is actually a tailpiece for a Tagelharpa! (I added holes for the strings after taking this photo)

As for the finish, I’ll just use oil, without sanding to preserve detail in the carving.

And here’s my cnc.
