ROLLING RULER

I found one of the most useful tools when ideating is the rolling ruler. This simple gadget allows the user to make accurate parallel lines as well as projecting angels. When researching for this project I found that, although the rolling ruler is widely used, it has several major downfalls, including damage to the paper, causing the ink to bleed, and easily being damaged itself. My goal was to solve the problem through design rather than by changing the material.
