[Robotgroup] Short but important survey

[Leslie Filip]

The 3D printers utilizing plastics make small non-circular loops that  
most people think are milling marks. In the case of the 4-legged  
robot, it looks like the guys did some additional finishing to smooth  
it a bit more. The slightly irregular surface you see in the photo is  
the result.
