Hello Ben,
I just wanted to submit an addon challenge to your 3D printer you built two Episodes ago. I realised how neet it would be to have a pair of 3D devices which you can use to scan an object and duplicate it as many times as you want with your printer. Not only could you physically replicate it but you can even use the 3D models generated by the 3D scanner for use in 3d design such as 3DMax and other applications.
My challenge to you is to build a 3D scanner that is big enough to scan a 6 foot tall person which can be exported to your printer (Object scaled down of course) or to a 3 application like 3DMax.
I think this challenge would be useful for us guys who like to build games which include objects arround us. And it would sure cut time with 3D Development too.
