Keychain Engineering Drawing

Overview

Turned a hand-sketched concept into a fully defined mechanical design for a small assembled keychain. Built a parametric SolidWorks model with all key features including body, loop, fasteners, and gear detail, with clear assembly intent throughout.

Design Process

— Created fully dimensioned drawings from hand sketch to lock geometry and features

— Modeled in SolidWorks with proper constraints and relationships so edits propagate reliably

— Designed internal mechanism and fastener layout for manufacturability — accounting for clearances, fits, and assembly order

— Generated detailed 2D drawings with critical dimensions and tolerances for fabrication

Results

— Build-ready documentation package including 3D model and 2D drawings

— Consistent, editable design thanks to parametric relationships

— Parts fit and assemble as intended with adequate clearances and specified tolerances

— Reduced fabrication risk and smoother assembly on first article
