The lasers are standard 12mm linelasers from ebay.
I have stopped further use and development on my TinkerToy scanner because the quality of the scans does not fullfill my requirements.
I have tried both the Frelss and the Fabscan software with same negative results.
In the future will use AgiSoft Photoscan. My very first test with photoscan based on 60 photos from different angles all around my object gave me an stl-file that could be sliced and printed without further processing other than aligning the object to the printbed.
So goodbye to laserscanning.
