GrabCad Model

I made a 3d Model to be made from laser cut parts that should be able to prove the viability of using stretched wire and a webcam microscope sensor.

The design uses two webcams to sense two suspended vertical wires with a weighted end suspended in Oil. This will guarantee that the two wires are parallel in two planes. This will eliminate any twist in generated surface, it will be a true plane.

I designed the mechanism using a laser cut frame and 100mm square tube and parts I have on hand.
There is minimal machining to do mainly small size lathe work.

To clear up any uncertainty The webcam sensor is moved mechanically until the image of the wire is Is centered on the webcam sensor. The size of the image will be determined by the magnification used. Small errors in the optics can be ignored as we are always using the same part of the lens.
