Our design challenge was to make an object with connectors on both sides. And the parameters were summer, uniformity, and lone star. So, what we made is a ball that has a bar with two locking buttons. To connect them together, you would press down on the locking buttons of one object, slide it into the back of another one, and let go. To meet the uniformity parameter, we made them all exactly the same. For the summer parameter, we made the back of our object a ball to represent the sun. And finally, for the lone star parameter, we made our locking buttons look like bullets.
