I've had an idea in my head for the last year for a new product. A product that does not currently exist in the market. I'm currently working on an aluminum/steel prototype, but this is merely as a proof of concept and to illustrate my idea. My ultimate goal is for this product to be injection molded plastic. What I need is a design based on my prototype, that I could 3D print for demonstration purposes and be able to take to a crowdfunding campaign and ultimately use that design and be able to modify it for my final product.
The attached image will give you an idea of an existing product that is similar to what I'm wanting to do.
