Carbon Fiber Mouse
I wanted to design the lightest possible computer mouse without sacrificing quality while keeping the cost low. At only 42 grams, this prototype has surpassed my expectations but the design still has a long way to go.
Surfacing
This project forced me to learn a lot about the surfacing tools offered by SolidWorks. The entire design is parametric, which is what has allowed me to change the shape between prototypes. This is important because mouse shape is incredibly important for performance and feel.
Carbon fiber shell
To save money and effort, I created a compression mold to form the shell of the mouse. The negative draft of the mouse required me to build the thing out of 5 pieces.
The compression mold strategy is pretty limited, as you can see in the right side of the mouse. Since the wedge does not distribute the force as evenly as the atmosphere, thickness is inconsistent.
Compatibility
This mouse is designed using the internals of the Logitech G305 for affordability reasons. I replaced the large, heavy AA battery with a smaller 150 mah LiPo battery and a TP4056 charging board. This also allowed me to add a USB-C charging port on the front, which is something too few wireless mice include.
