Battery spot welding jig

thingiverse

A straightforward and practical jig for holding batteries during spot-welding tasks, also seen being sold online. This handy tool can accommodate a single set of batteries ranging from 1x1 to 8x9 in size. Its modular design allows multiple components to be connected, thereby increasing the overall width or length of the bracket. I constructed this jig using 8mm anchor-style bolts, but I believe regular 8mm screws would also serve the purpose adequately.
