I'm going to be getting a 3D scanner

Wow... pricey but looks pretty precise! Probably also easier to use than this   https://philohome.com/scan3dlaser/scan3dlaser.htm

Heh, yeah not cheap by any stretch of the imagination but at least that one is made from actual lego.

Not really sure that amount of precision is needed but I guess its better to have too much than too little.

At least they have come down in price, a few years ago it would have been £10,000 if not more.
