Hi there,
This is Bogdan from Romania.
I'm a mechanical engineer, specialized in the industrial robotics, 3D modeler and designer.
I have over 15 years work experience, designing, prototyping and launching different devices/systems across multiple industries.
I could help with your project.
From what I see in the attachment you need several components/parts: the extruded rail (which should be delivered in several cad formats - iges/stp/stl for conformity, and dxf/dwg in order the manufacturer to adjust it accordingly with the machine parameters(it will be necessary to modify the shape, as any extrusion deforms while cool down), the lens, the mounting tray, and the caps(for injection molding).
For any other questions, you may open a chat room here and we'll discuss about the details.
Regards
Bogdan
