I can do 3D-models/parts for 3d-printing and concept generation. I am specialized in product development (mechanical engineer). If you want a 3d-model to be done please write to 3d360swe@gmail.com. I can handle ProE, Creo, SolidWorks, Inventor, Catia V5. Basic drawings can be done to complement your 3d-model. You always pay when you are satisfied with your 3d-model. You preview the 3d-model before payment so you are 100 percent satisfied. Don´t hesistate to write if you have any questions. You just have do send your basic drawings with the dimensions and I will do the parts for you then you can sell them on shapeways.
