 Computer Mouse
 
Project Duration: 6 weeks, Individual Tools: Solidworks, Cold working, Leatherworking↗, Prototyping
 This mouse is an exploration on how materiality can change our relationship with a product. The anachronistic use of hammered brass and leather tells a story of wear over time as these materials patina. Held together using only mechanical fasteners, the design emphasizes repairability and longevity.

One important design constraint was to stress repeatability in the manufacturing of a high craft object.








❷ Material Exploration
Exploring the combination of dissimilar materials excited me. Using both ancient and new age technologies led to a truly anachronistic object. 



Using 3D printed forms to wet mold leather allowed for complex geometry I could not have formed by hand. 


Coldworking the brass gave it the spring required for clicking actuation.


Polishing bronze-infused HDPLA maintained the precision needed for electronics. These are my tests polishing and heat treating samples. 




❸ Ideation
Much of my design process was led by modelmaking and experiments. Switching between sketches, CAD, the material experiments and carved foam models.

My shaping and proportions were led by mouse guru RocketJumpNinja, whose mouse reviews I’ve been watching since high school. The biggest rule is to maintain a 1x2 ratio in plan view. For a cohesive understanding of mouse ergonomics, I would recommend this video↗ of his.






❹ Prototyping
Each component had several iterations. The biggest challenge was translating changes to the metal and leather forms into the digital version of the mouse. 

The CAD was modified from the Bambu Lab wireless mouse,  making it easy to integrate the PCB with my desired form. 








❺ Reunion! One year later
I made 3 mice (and one working prototype). The two on the left spent the last year on display in the School of Design and the Coulter Welcome Center. The two on the right were used by my mom and an engineer friend who does all his CAD on it.

It’s exciting to have made a product that can withstand heavy use for such a long period of time. I really like to see how each mouse has weathered over time, especially the one on the far right.
