Want to modify a complex shaped plastic part; need a good, inexpensive, scan/service

[robosmith]

You need a reference point, to know how long your scan/photo is.

You know, I probably should have used a 2D scanner instead of a photo.

Seems like there may be a major market developing for inexpensive scanners that really work reliably.

And there's the rub.

Yeah, When recreating bulkheads for my boat (Which have a lot of radii in them, I gave up trying), I used a flatbed scanner, that way it gave me the exact edge.

Well, I think I've finally got a part that's close enough fit.

One surface that looked flat is actually sloped. My first cut had a same sized edge overhang all the way around, but the actual part varies continuously with a couple of notches.

All told I spent a good 5 hours and 3 prints. Would be nice if there were a good scanning service.
