Background

I've preferred cutting my own hair since middle school because I enjoy styling it myself. (As you might know, communicating exactly what you want to a hairdresser can sometimes be challenging.) However, trimming the back is particularly difficult due to limited visibility. I set out to design a simple, adaptable tool that would allow me to see the back of my head clearly while cutting my hair.

Design requirements

• Quick and easy setup
• No permanent wall mount
• Flexible angle adjustment with reliable locking

Design solution

• I decided to use my camera tripod with a ball head as the main support for holding the mirror. It can be set up within seconds, and the ball head enables precise and effortless angle adjustments.
• When paired with the existing wall mirror in the bathroom, the two mirrors create a clear view of all sides of my head, making self-trimming much easier.
• To connect the mirror securely to the tripod, I designed a custom adapter. The adapter uses a precise press-fit connection, achieved through accurate measurement and carefully planned offset tolerances for 3D printing, to ensure stability and ease of use.
