Problems that occurred with our previous connection pieces let us revise and form the latest and greatest. Our first problem that we were able to test right away was that the acrylic clips did not stay casted inside the rubber. Instead, they simply broke free of the mold. We determined that the way to fix this was to 1) make more holes for the rubber to cast through, 2) elongate the clip as a whole so it cast deeper into the structural rib, and 3) create small ribs to act as a grip. Theoretically, our modules would still be connected by the originally conceptualized middle piece and these new ribbed pieces.
