Daily Equation #15 - y = a*x^3

This is Day 15 of my collection of printable equations. To see the whole collection, go to: http://www.thingiverse.com/thing:227210

I'm continuing the series of polynomials today, with y = x^3 .

Details:
- units are in mm
- Range(x) = -50 to 50
- a = 1/2500

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.
