Since the shape of the object is correctly cylindrical, no changes are needed in that aspect. However, the size of the cylinder in terms of diameter and height is unclear. To address this, provide clear indications or markers on the 3D model that can help in determining whether the diameter is large and the height is short. This could be done by adding texture or markings that give a sense of scale. Remember, the goal is not to change the actual size but to make the size more perceivable.
