Nuki Smart Lock Pro Adapter for Abus Knob Knauf

The new Nuki Smart Lock Pro is no longer compatible with original Nuki adapters for locking cylinders that have a knob on the inside.
I have built this adapter for my Abus knob cylinder to match Nuki Smart Lock Pro and it works flawless.

In principle, the metal pin shown is not necessary, but I recommend using it so that the force distribution of the torque is spread over a larger area.
This requires 2 steps:

1. Drill a 2mm hole through the shaft end of the cylinder
2. Metal pin (e.g. a nail) of length 25-28mm, diameter 2mm
3. Assembly as shown in the photos

STEP-File included. Feel free to modify according your wishes
