Industrial 3D CAD product design for manufacturing/3D print prototyping

We are looking for a highly experienced product designer to design a prototype that can be easily 3d printed and later on iterated if necessary for production and copyright of the design in Australia.

Product will roughly resemble what a round hair brush looks like but needs to be designed so that when pressure is applied to the skin it has a rotating handle and is able to be moved across the skin gently and rotate on its axis. The material needs to initially be 3d printable and we need an experienced CAD designer who has worked on similar projects and has demonstrated success.

We would need to check with the designer if it is possible to design the prototype where the bristles can be 3d printed - this will depend on designer input and skill hence we need someone with lots of experience and that can offer advice and guidance upfront about this project and how best to get an MYP designed and 3d printed before registering and protecting the design
