VW Dashboard Holder Golf Plus Tiguan 17mm Ball

Solid Smartphone & MagSafe Mount – Say goodbye to broken air vent clips!

Most aftermarket phone holders and magnetic wireless chargers (like the Belkin Magnetic Wireless Car Charger WIC004) rely on air vent clips. Over time, heavy smartphones and road vibrations strain fragile plastic vents, causing them to loosen, break, or block air circulation.

This model converts your unused center console slot into a rock-solid, OEM-style 17mm ball mount to hold your smartphone securely in place.

### Key Features:

Universal 17mm Ball for Phone Holders:** Fits the Belkin Magnetic Wireless Car Charger perfectly, as well as all standard 17mm socket smartphone mounts and MagSafe chargers (UGreen, Baseus, ESR, Garmin, etc.).

Zero Vent Damage:** Relocates your phone to a stable, fixed position on the dashboard without blocking or breaking your air vents.

Extreme Mechanical Strength:** Engineered with 8 wall loops and high infill to hold heavy smartphones without shaking or snapping off.

OEM Fit:** Snaps directly into the factory slot replacing OEM card slot/blank part `5M0858373B` / `5M0858373D` without any permanent modifications to your interior. --- ### Vehicle Compatibility: Designed specifically to fit the center console slot for OEM Part Number **5M0858373B**: * **VW Golf Plus** (2005–2014) * **VW Tiguan 1st Gen** (5N Pre-Facelift 2007–2011) *

(Please double-check your original dashboard part number before printing to ensure exact fitment).*

### Installation Guide:

1. **Remove Old Blank / Card Slot:** Carefully pry out the original plastic switch blank or card slot using a plastic trim tool or a flathead screwdriver wrapped in tape.

2. **Snap in Mount:** Push the printed mount firmly into the empty slot until the retaining clips click securely into place. 3. **Attach Phone Mount:** Loosen the ring nut on your Belkin/17mm phone holder, snap the socket onto the printed 17mm ball, and tighten the ring nut. ---

Important Print Orientation for Maximum Strength:

Please maintain the exact orientation shown in the project file and preview image (flat on its back, with the 17mm ball and mounting clips pointing straight up). **Why this orientation is critical:** 3D prints are inherently weakest between layer lines. Printing the component flat on its back forces the load from holding your smartphone to run perpendicular to the layer lines. This guarantees that the 17mm ball neck and clips will not snap off under load, when mounting your phone, or when driving over rough roads! ---

Print Settings & Material Strategy:

This profile is optimized for a single-material **100% PETG HF** print: * **Material:** **PETG HF** (Crucial for heat and UV resistance inside hot parked cars). * **Wall Loops:** **8** (Provides extreme rigidity for the ball, neck, and clips). * **Infill:** **45% Gyroid** * **Layer Height:** **0.16 mm** or **0.20 mm** * **Ironing:** **Disabled** --- ### Support Configuration (Pure PETG): Since this is a full PETG print, proper support gap calibration is set in this `.3mf`: * **Top Z-Distance:** Set to **0.16 mm** (matches layer height) to ensure easy support removal without fusing the supports to the main body. * **Support Type:** Normal/Tree supports enabled for overhangs under the ball neck and mounting clips. --- ### Credit / Attribution: Based on a public Onshape base geometry, heavily modified and optimized with an integrated 17mm ball mount, reinforced clips, and custom print parameters.
