X-COM3 Slot Adapter for Cardo Freecom

NEXX X-COM to Cardo Intercom Helmet Mount Adapter

Upgrade your motorcycle ride with this custom 3D-printed adapter designed to mount your Cardo Intercom system seamlessly into the native NEXX X-COM port of your helmet.

Instead of relying on bulky adhesive pads or awkward clamps that interfere with your helmet's shape, this sleek adapter clips directly into the factory X-COM cavity for a clean, aerodynamic, and integrated finish.

Key Features

• Perfect Fit: Engineered specifically to utilize the OEM NEXX X-COM mounting slot.

• Tool-Free Snap-Fit: Quick and secure clip mechanism — no permanent modifications or messy glue needed.

• Aerodynamic & Low Profile: Keeps your Cardo unit flush against the helmet shell to reduce wind resistance and noise.

• Universal Cardo Compatibility: Works with standard Cardo clip mounts (Packtalk, Freecom, Spirit series).

Detailed 3D Printing Recommendations

To ensure maximum durability, vibration resistance, and weather protection, follow these sliced setup tips:

Material Selection

• PLA (Prototyping / Basic Use): Easy to print and sufficient for testing or temporary use. Note: PLA can deform under direct summer sunlight or high heat inside a parked motorcycle bag.

• PETG (Recommended for Everyday Use): High toughness, excellent layer adhesion, and good resistance to outdoor temperatures and UV exposure.

• ABS / ASA (Best for Ultimate Durability): Superior UV and heat resistance, ideal for severe weather and long-term outdoor exposure.

Recommended Slicer Settings

• Layer Height: 0.16 mm – 0.20 mm (Lower layer height improves clip detail and strength)

• Wall Loops / Perimeters: 3 to 4 walls (Crucial for structural integrity of snap-fits)

• Top/Bottom Layers: 4 to 5 layers

• Infill Density: 25% – 40%

• Infill Pattern: Gyroid, 3D Honeycomb, or Grid (Avoid lines or rectilinear for functional parts)

• Print Orientation: Position the model flat on the build plate to align layer lines perpendicular to the clipping forces for maximum clip strength.

• Supports: Tree Supports (Auto) recommended for clean overhangs and clip overhang details.
