About this 3D model

Besides making awesome key chains, wave springs are very cool. It's easy to design your own. I did the tall one in Solidworks with the equation: x = 1*sin(t) y = 1*cos(t) z = 0.125*sin(3.5*t)+0.075*t with x(t) = radius*sin(t) or radius*cos(t) y(t) = radius*cos(t) or radius*sin(t) z(t) = amplitude*sin(number waves*t) + (if you want it to grow upwards) (spacing*t) The cross section is a rectangle. I did the short one in Inventor with the Cylindrical equation: r = 1 phi = t*360 z = .25(sin (t*360*5)) The cross section is a circle since Inventor is weak with controlling your sweeps. I guess at least that program lets me have a closed loop. http://www.youtube.com/watch?v=zg1LRE0V7S4
