Wide feet with Logo for Printrbot SImple Metal

I really liked the wide footprint feet by @Thorped, and remixed by @Teljemo, but I have not ventured into flexible filament yet.

I did, however, have some extra vibration isolation thingees that I originally got for a quadcopter, but they were too big, so I modified the design to work with them.

I have no idea where I got the vibration reducing balls, but [something in the ballpark on amazon](https://www.amazon.com/T-Trees-Vibration-Anti-Vibration-Quadcopter-Photograpy/dp/B00ZFEVAJ6/ref=cm
