Replacement Nut for Fixed Wireless Car Charger (17mm Ball Mount)

The Problem: The original plastic nut on the Fixed wireless charging car stand (and many similar generic holders) is prone to cracking under stress or temperature changes. Once cracked, the phone holder can no longer hold its angle and becomes loose.

The Solution: This is a reinforced replacement nut designed specifically for the 17mm ball mount system used by Fixed and many other manufacturers. I designed this "V2" version to be robust and fully functional.

Compatibility:

• Brand: Primarily tested on Fixed wireless charging stand.

• System: Standard 17mm ball joint (common in Garmin, iOttie, and many generic phone mounts).

• Note: While the ball is standard 17mm, thread pitch can vary between manufacturers. This is tested and working for Fixed chargers.

Print Instructions:

• Material: Strongly recommended to use ASA, ABS, or PC.

  • ⚠ Do not use PLA: Temperatures inside a car in summer can easily exceed 50°C-60°C, causing PLA to deform and the holder to fail.

  • PETG might work for milder climates, but ASA is superior for UV and heat resistance.

• Infill: 20-40% (or 100% for maximum durability).

• Perimeters/Walls: 3 - 5 perimeters recommended for thread strength.

• Layer Height: 0.12mm or 0.20mm (lower layer height ensures smoother threads).

• Supports: usually not required if printed with the flat face down.

Installation:

1. Remove the cracked original nut.

2. Slide this printed replacement onto the ball joint first.

3. Snap the ball into the socket.

4. Screw the nut onto the threads. Do not overtighten with tools; hand-tight is sufficient.

Happy printing and safe driving!
