I need detailed 3D images for manufacturing specifications. The products are very simple - a round flat top with a hollow cylinder attached. I need this in 2 sizes. The images should include: - Exact dimensions Ideal skills and experience: - Proficiency in 3D modeling software - Experience creating detailed manufacturing specifications - Attention to detail and accuracy Please specify the file format you can deliver in (STL, OBJ, STEP). I am not sure of the file format as this 3D rendering is to provide to vendors to get a few quotes.
