As a follow-up to this comment, I'm uploading the mirrored version of this great model, with a plus capability where you can place the cables on the side.
There is no need anymore for a USB-C extension cable.
As the original model, made with the personal version of Autodesk Fusion 360 therefore non-commercial only.
Source files included.
The author remixed this model.
1. Increased the 'watch holder' hole to fit the original cable plug.
2. Removed the connection piece from the left pegs.
3. Open a hole to pass the cable by the side
4. The model was horizontally mirrored, just for my pannel esthetics
