Older pinball machines have batteries to save the settings and high scores. Sometimes we forget to replace the batteries and they leak on the CPU board, possibly ruining it. One common way to avoid this is to relocate the battery pack to another part of the back box. This model mimics the batteries for the common 5881-09021-00 battery holder found in Williams and Bally WPC and System 11 pinball machines (possibly others) to create a remote battery holder without soldering anything.
You'll need 2 screws and 2 nuts for the connections, M3 for the bottom, and M2 for the top. The nuts will hold down the wires making a solid connection.
I recommend not printing this in PLA as it may melt in the heat of the backbox.
Up Fila ABS
Would not recommend printing in PLA as the inside of a pinball machine's backbox may get hot enough to melt it.
After printing, sand the curved bits so it will fit properly. Batteries are difficult to insert into the battery holder, best to avoid having to force it.
