cults3d

In Part one of this lesson can be found here: http://www.thingiverse.com/thing:1733354 This, part two, lesson is designed to have student demonstrate the concepts of the parts of an inch. The student is only tasked with representing the concept not that their ruler is true to scale. In fact reviewing the concept of scale is a great idea and this lesson lends itself to that very well.
