VW Golf Mk4 Dashboard Phone Holder (Parametric, Fits S23 Ultra + Custom Sizes)

(imported from thingiverse)

I bought an old Golf Mk4 last week (May 2023) and remixed nUmbinho’s “Golf 4 PDC Holder” to create a proper phone mount for my Samsung Galaxy S23 Ultra. Their original model fits perfectly (great work!) so this design builds directly on that footprint.

This version includes:

• A phone holder sized for the Samsung S23 Ultra (with a phone case)
• A fully parametric FreeCAD file so you can adapt it to any phone
• Adjustable dovetail tolerances
• Optional charger-hole alignment controls

Parametric Customisation (FreeCAD)

Open the FreeCAD file and modify the values in the spreadsheet named “v”:

• PhoneWidth
• PhoneHeight
• PhoneDepth
• ChargerHoleOffsetBottom
• SlotWidth (dovetail tolerance)

After changing the parameters, you may need to recreate the chamfers if FreeCAD complains.

Print & Fit Notes

The sliding dovetail joint fit depends on your printer’s dimensional accuracy and print orientation.
On my Ender 3 V2, a 0.3 mm clearance produced a firm but workable slide. Feel free to tweak SlotWidth if you want a tighter or looser fit. For example, on my newer Elegoo Centauri Carbon, I eventually used a SlotWidth of 0.1mm.

Print Settings (my setup)

Printer: Ender-3 V2

Layer height: 0.2 mm

Infill: 20%

Supports: Only for the dovetail/charger slot (it can bridge, but may be tight)

Rafts: No

Feel free to message me or comment with ideas, improvements, or remixes. I’d love to see what other people do with the parametric version!
