Battery Terminal Cover Caps

This is a bit of a bonkers project that I came up with while I was working on my car. It's simple though.

I found that I had to regularly disconnect the battery and found myself with either nowhere to easily place the lead or having to rely on a plastic bag to secure it.

These cover caps no only isolate the battery but the taller posts mean it provides a suitable location for you to place the lead. These are for a standard 12V car battery. The main image shows the generation 1 cover caps but the file attached is the generation 2 which covers the terminal more completely.

3D Printer - sorry

PETG filament in Red for positive cover

PETG filament in Black for negative cover

I designed these caps in Fusion 360 which is an incredible piece of CAD software and is the next generation on from TinkerCAD (also fab btw). I checked the standard terminal specifications for a car battery and designed this before exporting as a .step file.

Download the step file and import into your slicer of choice to print the files. The Black cover cap is for the negative terminal and is slightly smaller in diameter than the Red cover cap which is for positive terminal.

I printed these on separate plates using standard PETG settings on the printer I have and they worked great and have now been added to my toolbox.
