Jill,
I had tried Qlone - a phone based app for small objects. You print an alignment grid and then use phone based photogrammetrics, no laser, to scan the objet. We also have a David scanner which uses structured light.
My guess is that all of these low cost systems are OK for documenting an object but not for accurately reproducing something. My limited understanding is that the physical alignment of the camera (s), projector/laser very important and that the alignment in the field is not a great substitute for actually having the alignment built in.
I hope I am wrong. It would be great to have a useful low to mid priced scanning solution as it is something that is useful to us every now and again but hard to make money at $20K+
