Improved Trap

I found that the structure of the trap on the same site had some issues. One was that the rubber band's lever arm was almost non-existent, leading to almost no retraction force in the open state. Also, the pivot was 3D printed, resulting in severe friction and making it very difficult to trigger. Secondly, the base was pieced together and prone to breaking. I heavily redesigned the structure. It requires two 5mm*40mm pins to serve as pivots, which makes it much smoother. Use one rubber band on each side, and pay attention to how they are tied.
