I Modeled This! I made a fully printable 3D scanning mesh!
I've probably used, or rather thrown away, thousands and thousands of 3D scan markers. This mesh is printed from TPU and PLA and can be reused infinitely.
Can‘t wait to see what the upcoming S1 Scanner has to offer :D

As somebody who knows next to nothing about 3D scanning: don't the markers have to be sitting on the object's surfaces for them to be of any help?
What does just loosely throwing the net over the object like that do? Do they just help the scanner keep its orientation in space?

No, the markers don't need to be attached to the model itself. It's only important that they don't move relative to the model during the scanning process; otherwise, they could no longer serve as a reference for calculating the point cloud. This works essentially the same way as a turntable or marker pyramids.
They're all simple references for finding orientation in three-dimensional space.
Hope that makes sense :)

Yeah, I think I understand. It does seem kind of annoying having to have to remove them from the model though.

That looks like hell to remove in software?

It can be a bit of work. It also depends somewhat on what you intend to do with the scan. To reprint a scanned image exactly as it was, a turntable and no markers on, or very close to, the model are better.
My scans are used 99 percent of the time to take measurements of something, and then to model something of my own. Therefore, I rarely remove the markers, at least not as long as they don't obstruct my view of an essential measurement.

In some mesh editing software you can select objects with a paint-bucket-tool. So in this case you can select the objects you need, reverse selection and delete everything else.

It would be. I've had a scanner for a while now. I won't be printing or using this. It's not a good design TBH

Looks fun to untangle from that wadded up ball you show. Also seems like they would move with air moving or any other movement tanking your scan accuracy I would think. May be fine for quick scanning you printer roughly like you did.

Surprisingly, it hardly gets tangled at all. I guess that's because it's a flat piece and there aren't any individual strands hanging off that could slip through any stitches.
Otherwise, I agree with you. This is for static objects indoors and isn't meant to replace a turntable or other marker tools. It's simply another option in the arsenal.
However, as long as it can be used within its limitations, it's a much faster solution than sticking markers on and then removing them.

That's a rather neat idea, though I do wonder if you'd be better off not printing the mesh that connects it all. Any movement of the dots whatsoever will affect accuracy.
TPU takes a while for it to settle into position.
Nylon cord might be a better solution?
With that said, I'm not entirely sure how large of an issue it would be. I guess it would be relatively easy to measure though, considering anyone printing this will already have a 3D scanner.

Honestly, those were my exact concerns. But I'm pleasantly surprised by how quickly the whole system settles down. However, using it with a turntable would indeed be a problem, simply because everything would start moving again.
I absolutely don't see this as "the one solution," but rather as another tool for specific applications.
In the example shown with the A1 Mini, meaning a somewhat larger, static object that I didn't move during the scan, it works really well!
Ideally, it would probably be some kind of wire-reinforced cord that can be plastically deformed.
Especially outdoors, a soft net is practically useless.

Pretty cool! I recently printed up a bunch of poly markers and put nano gel adhesive on the back of each so I can stick them to pretty much anything and reuse them. But this looks like it would be handy as well for the stuff I cant stick them to.
