That would be wonderful. Thanks! Let me know if you get your printer online.Your ground (negative) lead should be ok like it is, but assuming the positive is uncovered I think you should be able to get something 3D printed that will cover it nicely. It's not rubber/soft but should work for safety/fire/arc prevention. If I could get my 3d printer online, I'd make you one and just get you to send me a shipping label. HTH.
It just seems odd that nobody already makes a cover that would work for two wires. My situation can’t be unique.
And yes, I’m really interested in the positive terminal. But I have corrosion buildup on that one and didn’t want to get the conversion off-topic if people saw this corrosion. The positive terminal has the exact same two wire setup.
