About this 3D model

On this part: http://www.thingiverse.com/image:57507 You can see some damped oscillations after the logo. I made this thing to try to get a better look at them. The photos were taken of a part built on MiseryBot which has a lowrider. Printing was at 40mm/sec Someone with mote math skilz than me might be able to draw some conclusion as to what the waves mean.
