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

1. Adjust the size of the horizontal section of the "L" shape to make it significantly smaller than the vertical section. This will ensure that the "L" shape is more pronounced and distinct.

2. Introduce a slight curve to the vertical section of the "L". This will add a unique characteristic to the object and differentiate it from a standard "L" shape. 

Please ensure that these changes do not affect the overall "L" shape of the object and its extrusion in one dimension.
