Based on the answers provided, here are the corrections needed for the 3D object:

1. The object needs to be redesigned to resemble a ring. This means it should have a thin, circular band shape rather than a cylindrical shape with a hollow center. 

2. The orientation of the object's extrusion needs to be clarified. If it's not already, ensure that the object is extruded along the x-axis.

3. Ensure that the object's extrusion is uniform along the x-axis. If it's not already, make adjustments to ensure uniformity.
