I am a modeler with experience in mechanical design. I use an advanced software called SolidWorks which is capable of producing extremely accurate mechanical models. While the software, and my experience lacks the ability to create un-dimensioned abstract art or sculptures, the software is the perfect fit for someone looking to translate their 2D gear into a 3D model or to create some sort of mechanical part.
My experience in SolidWorks goes from engines to transmissions to iPhone cases. I can at least attempt any design you are wanting and will not charge a fee until you are purchasing your final model!
