My esteend listmates, For our 3D printer, I'm trying to scan a photo of an object so I can then get accurate measurements of that object. Poly Cam did an excellent job on my Android cell but to save that scan they require you to pay $80 for a premium account. Have you found any phone scanners which are accurate and better priced? I found this but I don't know how much I can trust reviews? https://www.nytimes.com/wirecutter/reviews/best-mobile-scanning-apps/ Thank you. Charles. Charles Meyer Charlotte County Public Library
