This is a dummy AA size battery:
It will not work on its own - it only passes through amp & current from other batteries.
The dimensions are taken from this spec, it seems to be working so far...
You will need:
The printed part (no more than 40% needed)
1 M6x50 Hex socket head cad screw
1 5mm Allen key
1 Metal file (to de-burr the tip of the screw)
(A better pen than mine to highlight the DUMMY on the side)
