Hi there,
I'm a mechanical engineer with over 15 years experience in designing, modeling, prototyping and effective manufacturing of different products, ranging from consumer goods to alternative energy systems.
You have a very interesting product and will be challenging to design it, but I want in!
As engineer conducting different documentary research, I could also help you with avoiding some patent infringements - there are many different bottle plug openers (see [login to view URL]) and for sure they are patented. I like to think you already made your own research on this.
What I'll deliver: 3D model of the opener and its components in different CAD formats (ipt, iges, stl, step, obj, etc), 3D pdf for the assembly and components so you may open the file with regular Acrobat Reader and manipulate the model (orbit, zoom, pan, slice) and execution drawings with BoM (bill of materials).
