The bust would typically depict Clayface from the shoulders or neck up. Clayface is known for his distinct, malleable form that can take on various shapes and sizes, often appearing as a large, lumpy figure with exaggerated facial features.
The level of detail in a 3D-printed bust can be quite high. Key details would include the texture of Clayface's "skin", his exaggerated facial features, and the unique, flowing shape of his form.
Please note that the specifics would depend on the 3D model used for printing. If you have a specific model or design in mind, please provide more details, and I'll do my best to give you a more precise description.
