DIY Malectrics V2 Battery Spot Welder Probe (Upgrade)

I am upgrading my DIY Malectrics V2 Battery Spot Welde probes to solid 6mm x 200mm round copper stock.
I have created a prototype Fusion 360 3D printed holders for the 6mm copper. I will upload it to Thingiverse once I have finalised it.
I definitely recommend using crimp lugs instead of soldering the copper wire to the 6mm copper round stock, but I currently do have access to any and will do this in the future.
My car battery is getting a bit old so I think the final result could be improved by using a better condition battery.
