Daily Equation #11 - y = sin(cos(x/7)+sin(x))*x

This is Day 11 of my collection of printable equations. To see the whole collection, go to: http://www.thingiverse.com/thing:227210

Based on plastic's request in the comments, (http://www.thingiverse.com/thing:231587/#comments), for today's equation, I'm doing y = sin(cos(x/7)+sin(x))*x. I've included the Openscad file in case someone wants to modify the text or stand.

Details:
- There's a surprise guest in the pictures.
- units are in mm
- y scaled by 0.5 and x scaled by 1/9 to k
