Sketch to CAD-Style Line Art Conversion Prompt

Please finalize this rough sketch and create line art. Read and refer to the blue text annotations, eliminate the ambiguity and roughness associated with handwriting, and create precise line art as if output from a CAD tool. Vary the line thickness, such as making ridge lines thicker. Delete the blue text and lines, and do not include them in the output image. Please finalize this rough sketch in the same manner.
