Arri WCU-4 Wireless Follow Focus case

I bought both the Arri WCU-4 case and the Movi Pro larger case. I am happy with both but the WCU-4 case the compartment for the charger is not the right size so I had to cut the foam. The charger for the WCU-4 batteries is large, Sony BC-QM1, I think there use to be another smaller charger but Sony discontinued it. If you changed the size of the battery charger compartment of the WCU-4 case it would be perfect.
