I am looking for a CAD designer to develop the window opener. We are using Stepper motors to lift the vertical sash window. I need to design the mechanical part for the product version. The designer should design the enclosure and mechanism including lead screw, carriage, etc. I attached the images. You can refer to the commercial window opener and stepper motor lead screw. The designer can use Solidworks or Fusion 360. The window weight is about 10 Kg and we use nema17 42 motors.
