As a matter of capturing the query- I have an iPhone with Lidar, and have tried some scanning with it using an app called KIRI and another called Scaniverse. They do an interesting thing, but what I’m finding is that OBJ files have no scale attributes. It’s all polygons or something without reference to how big things are supposed to be (or what the scanned object was), so printing from them is fussy.

Mohawk and blue eyes to this and make a cousin of Geoff Peterson (I miss me some Craigyferg and Grant Imahara). The snag is that I have to measure two constant points like cheekbones or eyes center to then tell my CAD how big it’s supposed to be. There simply must be a better approach.
KIRI makes a great looking model though- it overlays camera data over the shape and wow. Example:
