I need to replace the USB cable on my Brodit car mount for a new usb-c to usb-c one. The Brodit mount wants a rectangular profile cable which seem impossible to actually buy in the length I wanted. I ended up with this cable, https://www.ebay.co.uk/itm/125861365896, with an oval profile.

This part replaces the original USB-C cable holder found on the Brodit universal USB C holder 521844 (https://www.brodit.co.uk/brodit/holders/_/_/521844.htm) using the original screws.

I've included my FreeCAD file in case you want to change a dimension to suit a different mount or cable.
