We would like to create a 3D rendering that can be used to print a prototype of our product. I have included pictures of a product that is the same thing. We want to create this product then make some changes to the product to include the company logo and information engraved into the casing. We would also like to print a prototype before manufacturing, and then once we like it, we would like to set up manufacturing a large quantity. Please send me sample of what work you've done that is similar.
