We're excited and proud to launch Thingiverse Apps. Learn More about what this means to you.
This is an automated 3d david scanner I made for 3d scanning. It uses a stepper motor to rotate the object and an RC servo to raster the line laser across the object.
video of the setup in action can be found here:

scanning software : http://www.david-laserscanner.com/
the automation software is written in visual basic
a sample scan can be found here: http://www.thingiverse.com/thing:102319
I have attached the source code to the automated VB6 program used to automate the scanning process along with an installer. A brief explanation of the software can be found here: http://www.youtube.com/watch?v=ChfcFeCMLHA
I am also using com0com virtual null modem cable to communicate with the david scanning software. This allows me to use the same PC for automation and scanning. This can be downloaded here: http://com0com.sourceforge.net/
I am using 6mm thumbscrews to secure the base, camera mount, and servo controller mount. a 5mm set screw secured the line laser. Tap these holes.
I am using a 1/2" wooden dowel as the vertical upright.
