Hi there,
This is Bogdan from Romania.
I'm a mechanical engineer, designer, modeler and inventor with over 15y experience in designing, modeling and effective manufacturing of different products, devices and systems which spans across multiple industries.
I could make this model for you but I'll need a section view and dimensions.
I'l make the 3D model accordingly with ISO standards (or if you prefer ANSI/DIN, or whatever) and I'll deliver 3D model and its components in different CAD formats (iges, step, sat, stl), 3D pdf and execution drawings.
Based on your input, I'll make a rough model on which you'll ask for modifications/adjustments (if any). Once the model finished and aproved, I'll detailing any feature and generate alternative files.
