This is a simple nuki smart lock adapter I have created for my KABA lock. In the final result I have printed in 70% infill to make it stronger - fill free to tweak this as you wish - but bare in mind that this needs to be strong :) I have made a small update in v2 - made the screw hole a bit smaller - so the screw will create it's own thread more tightly From: https://www.thingiverse.com/thing:4969615
