ninebot f2 controller punch/pusher??

I made this very rough and ready block to fit between the Ninebot controller and the metal casing. The idea is to hopefully reduce the damage done to the circuit board while trying to persuade it out of the casing, as I needed to access some solder points on the back to flash custom firmware (CFW).

Hopefully, this will save someone a couple of minutes designing this very basic block.
