Set fixed position for a specific game object

Hi! I have a factory, which creates some game objects, while camera (I use orthographic) is moving in the scene.
I would like to set this factory to some fixed screen position, so it would be like gui and it won’t change its position all the time while camera is moving.
Do I need to check camera position in each frame and relocate my factory depending on that or there is possibility to set it to fixed screen position without calculation and relocation this factory?

Could you maybe child the factory game object to the camera game object and give it an offset?
