Hi Juan,
My name is Tom, I'm a Mechanical Engineer from Australia.
I have a lot of experience with 3D Modelling and can take your home-made prototype and turn it into a set of professional drawings and 3D models with ease.
Since this is a home project, happy to do it cheaply and make sure you're 100% happy with the final product.
Feel free to message, Happy to negotiate a reasonable price and answer any questions or comments you might have.
Many Thanks,
Tom
