Official ERGO K860 CAD Template

Official Reference CAD Envelope for Logitech ERGO K860

Provided as part of Logitech’s Adaptive & Accessibility Initiative, this package contains a simplified 3D reference model (dummy CAD envelope) for the Logitech ERGO K860 Wireless Split Ergonomic Keyboard.

COMMUNITY-DRIVEN UPDATE:

Based on your feedback, we’ve increased the level of surface detail on this model to help you design higher-precision accessories!

Design Considerations & Model Features:

• Outer Bounding Geometry: Accurately represents the complex curved chassis profile, split-key elevation slope, integrated cushioned palm rest contours, and overall clearance zones.

• Enhanced Functional Details: Includes exact references for retractable tilt legs, battery door access, On/Off switch placement, and charging port clearance.

• Suggested Use Cases: Ideal for designing custom negative-slope desk wedges, wheelchair tray mounts, keyguards, tactile indicators, or auxiliary palm support extenders.

• Non-Destructive Design First: We strongly encourage creating attachments, clips, or brackets that cradle, clamp onto, or slide beneath the device. Do not attempt or encourage disassembling the hardware, as opening the chassis voids warranties and risks damaging internal battery components.

• CAD Compatibility: Provided in universal STEP format, making it easy to import into Fusion 360, SolidWorks, Rhino,, for instant accessory design.
