Custom Keychain

Design and Manufacturing Project

Custom Keychain

Project Overview

I designed and machined a custom aluminum keychain with a fidget spur gear. I first designed the keychain in SolidWorks, then created drawings based off those designs. I then machined the keychain following these drawings using a bandsaw, lathe, and manual mill. This project was a fun way to practice my CAD, drawing, and machine shop skills!
