BMW E9x Jack Point Adapter Custom-made
User @Ninefifty has done an amazing job at creating his own Winntec jack adapter for lifting his BMW E91. Download his files to 3D print your own or show your support to him here.
Made to fit a car jack from manufacturer Winntec, but will probably fit others. I own a E91 and modelled it for this one, but i suspect all E9x models share the same jacking points.
The original Winntec jack insert had a hollowed out (1mm) centre which i copied, there is a included support for this part. After printing you can rip this out if needed for your jack. Best material would be TPU with some good amount of infill.
