Some Cube bikes (like my LITENING AERO C:68X RACE) come with a Cube mount for Garmin / Sigma devices.

I created 2 adapters which can be used to attach the Quadlock system to the Cube mount.

Version 1: this is a flat version which allows the Quadlock system directly sit on the Cube mount. This might by anyhow be in conflict with your bike's handlebar. Therefore I created Version 2

Version 2 ('high'): I added a spacer of 8mm in order to fix the possible incompatibility with the handle bar

Basis for the adapter is the PopSocket Adapter V2. I reduced the diameter and added screw holes

I also used the M5 nut from mike_mattala's NutJob (/thing:193647) and integrated it into the PopSocket.
