Open the model and look at each step to see how it was done.

1. Step 1:

   First create a ball and then an intersecting axis using the top and right planes
   

   

2. Step 2:

   Create a circular pattern of your balls around the new axis
   

   

3. Step 3:

   Sketch a band on your front plane
   

   

4. Step 4:

   Use mid-plane to extrude your cage band, but UNCHECK the "merge result" box
   

   

5. Step 5:

   Sketch a slot on your top plane and make a cut through only your band by selecting on the band as your cut body
   

   

6. Step 6:

   Make a circular pattern of the previous cut around the same axis using the same number as the balls you patterned
   

   

7. Step 7:

   This should complete your cage
