This is the 30$ scanner I found on thingiverse http://www.thingiverse.com/thing:1762299 except it has its own motor instead of runnig manually.
The motor (C900) and gears are from an old HP printer I recycled but it's not powerful enough to hold more than 500g.
The ball bearings are used ones from my roller skates, hence the squeaking sounds.
Since I didn't use the recommended 3dprint settings, this build is horrible, warped, overextruded.
The result is a very shaky base moving irregularly while sounding like it's agonising.
