In the upper Midwest, we go ice fishing (hardwater fishing) during the winter. Anglers go out on the ice and use shelters to stay out of the elements. In the shelters, you use lights, fans, fish finders, etc. These things all use 12-volt DC power. To supply this power, you need a battery.
One night, while in my shelter, I hooked my lights and fan up to fish for the evening bite. I was all set. Until I moved and bumped the battery. My alligator clip was knocked off the battery, and it went dark. Then I went into pure darkness. I was very frustrated with the situation.

This is when a lightbulb came on in my brain. The battery terminal optimizer was born. I produced this great idea that would solve all my problems. I just had to take my idea and make it a reality.
I searched the internet for a cheap solution to my problem. Yes, I did find a product that I could make work, but it was too expensive. So, I kept searching and produced no other products.

So, I spent a week or so planning on how to make it. Next, I started to look for components for my idea. I came up with the idea of 3D printing the body and buying the rest of the components from an electronics catalog. I talked to a friend about 3D printing the body. I had decided to use ABS filament for the body. He set me up with a printer, and I proceeded to the next step.

I went on the Internet and found a free CAD software to draw my part. After some time, I figured out how to use the software. I had just drawn my first prototype. It was far from perfect, but at least it was a start.

So, I ordered my other components and the abs filament. After 5 days went by, they finally arrived at my house. I was excited, but everything did not go together as I predicted. I had to go back and make some changes.
After a month went by, a lot of bad 3D printed parts, and many revisions, I produced a part that would work as I wanted it too.

The Battery Terminal Optimizer is a very ingenious piece of art. It takes the positive terminal and the negative terminal of the battery and multiplies them. It turns the terminal into four terminals. Four for the positive and four for the negative. Now, I can attach four different devices independently to each other. No more having to clip alligator clips to each other.
I went out fishing the next week, the Battery Terminal Optimizer did its job very
