The file '18650 8.4v Battery Pack 3D Printer Model' is (123dx,stl) file type, size is 1.0MB.
I used the following BMS Board, though i am sure others will fit if you hollow out the original design file.

I use an old 8.4v sony camcorder charger to charge it. cost £1 at a car boot sale.

To anyone who has already downloaded it, i uploaded the wrong STL, it has no hole for charger output connector, I have amended the stl and uploaded it. My apologies if you have started print.
