Broke my flex shaft

I had my dremel on my workbench with the flex shaft attached.  I was using it and it slipped out of my hand.  The flex shaft did not hit the ground as my workbench is rather tall.  When I picked it back up and tried to use it the bit in the flex shaft did not turn so I took it about and this is what I found, the wire snapped inside the flex shaft..  I am not blaming anyone for this happening, this is more of just an FYI for this using a flex shaft
