Did you happen to look into Open Scan? It's reasonably open and is PI based. I don't know a ton about them, but it seems like a viable alternative at first glance.
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.
Thanks for the reply, I was genuinely curious and haven't looked into this much beyond window glancing.
I've done some level of flatbed scanning with a ruler to get a known scale and the results have been pretty consistent, but I totally get not wanting to be size limited. I generally print bigger things, which is one of the reasons why I haven't looked at a scanner very hard.
That's an interesting use case that I hadn't considered. Makes sense that you want portable and adds the extra challenge of likely not being able to touch the object being scanned.
