Hi Schiffy and welcome to MySwissAlps!
You can store your luggage at Zurich main train station or Zurich airport. You can then send the luggage on to Basel later in the week.Read more about Swiss railways luggage services here.
You would, as far as I am aware, have to return to your luggage, pick it up and then send it off. I'm not sure if you were looking for a service to do that without you going back to Zurich?
