About this 3D model

This is Day 13 of my collection of printable equations. To see the whole collection, go to: http://www.thingiverse.com/thing:227210 Things are a little hectic this week, so I decided to go with something simple, a line, y = m*x+b (http://en.wikipedia.org/wiki/Line_(geometry)). M is the slope of the line, while b is the intercept on the y axis. Details: - units are in mm - Range(x) = 0 to 100 - a = 1, b = 0 As always, I'm going to continue to post one equation per day until get bored or people lose interest. If there's a particular equation you'd like to see, leave a comment and I'll give it a shot.
