Summary:  The arm band will fit exactly in the back of the unwearable shield,, 

 i made the band shell 4 and the infill 15 percent,, so light but still strong ,, 

the size is a bit large so i made a ring to make it smaller it slides in well if need smaller just resize the inside of the ring insert so any size is make-able this shield
