Powerbank

I have some cells from warrantied Parkside smart battery, so i made case for them with small powerbank module

The case is held together using threaded inserts (M4) and screws. 

The board is fitted snugly, but there is also place for M2 screw insert or really small wood screw.

There is also print in place “button pusher” for the push button on the board,  but in my print it fuses a little with the bottom so I'have to defuse it with exacto knife.

HINT: use some kind of cord around batteries before pushing them in case. It is easier to get them out that way
