For my final project I decided to create a mini breadboard holder that attaches to an Arduino uno. For anyone who has used an Arduino, they would know how annoying it is when the breadboard is freestanding and moving around all over the place. This design in particular is really nice because it puts the breadboard right on top of the Arduino, so the whole setup is super compact. Because it’s a mini breadboard, there isn’t much that can be created with it, but it is a great learning tool as a whole because individual components can be tested very easily with it.

I printed it in 3 pieces, the bottom of the case for the Arduino, the top of the case, and then the breadboard holder. The hardest part of this was connecting the top to the breadboard holder. I had to design a special connector and iterate a lot of tests to finally get it to stick in.I went through 3 different designs of the connector before I stuck with my final one, which was a square on the bottom, a circle in the middle, and then a square above that. This way I could stick it into the square hole I made in the top of the case til it got to the circle part, and then rotate it 45 degrees so it stuck in. Below are some of the later test connectors I made.

And attached are some pictures of the final print:

And here are some of the designs:
