Geeetech A10 LCD 2004A 20x4 Display - CAD Model

Reverse-Engineered CAD Model of Geeetech A10 LCD 2004A Display

I couldn't find an accurate 3D model of the Geeetech A10's LCD 2004A (20x4 character display) anywhere online, so I decided to create my own by reverse-engineering the physical hardware. This model is now available for the community to use in designing custom enclosures, mounts, and integration projects.

What's Included:

• Complete PCB geometry with accurate dimensions
• All major components modeled (buttons, potentiometer, connectors)
• Mounting hole locations and specifications
• Multiple file formats for maximum compatibility

File Formats:

• STEP - For importing into any CAD software and making modifications
• STL - Ready for 3D printing applications
• FCStd - Native FreeCAD file with full parametric history

Perfect For:

• Designing custom enclosures for the A10 LCD
• Creating 2020 extrusion mounting systems
• Integration into custom 3D printer control panels
• Retrofitting older printer setups
• Educational purposes and maker projects

Key Features:

• Accurately measured from real hardware
• Includes critical clearances for all components
• Parametric model allows easy modifications
• Professional-grade CAD quality

Technical Notes: This model was created in FreeCAD through careful measurement of the actual PCB and components. All dimensions have been verified against the physical hardware. The model focuses on mechanical accuracy for enclosure design rather than electrical details.

Community Contribution: Since documentation for older hardware like this can be hard to find, I'm sharing this model freely to help other makers and engineers. Feel free to modify and adapt for your specific needs!
