Beetleweight Battlebot
Over about two months I did most of the CAD for a 3 lb battlebot, including the drivetrain and weapon. We sketched the concept in Onshape, moved it into SolidWorks, and went through three iterations of the drive base and weapon before settling on a design. The bot worked, but the motors and electronics ended up interfering with each other and the motor mount was too fragile. It taught me more than most of the builds that held together.
