Based on the answers provided, the following corrections need to be made to the 3D object:

1. The object should be redesigned to resemble a taut bike chain. This means it should have a segmented, interconnected structure instead of a solid, smooth surface.

2. The two circles should be joined by two lines that are tangent to both circles. Currently, the circles are part of the object's continuous surface and are not connected by distinct lines. 

3. The distance separating the two circles should be clarified to be approximately equal to the diameter of the larger circle. This may require adjusting the position of the circles or their size.
