Daily Equation #7 - |x^(5/3) + y^(5/3)| = a

This is Day 7 of my collection of printable equations. To see the whole collection, go to: http://www.thingiverse.com/thing:227210

For today's equation, I'm continuing the series of equations of the form |x^b + y^c| = a (See days 2 and 6). Previously, we saw that b = c = 1 generated a diamond, while b = c = 2/3 caused the diamond edges to curve inward. Today we look at b = c = 5/3, which bends the curve outward to start approaching a circle.

Details:
- units are in mm
- a = 678 (to g
