NUKI Fob Keyholder

prusaprinters

<p>This is a keyholder with integrated Nuki Fob.</p> <p>Warning: For this keyholder you have to disassemble a Nuki Fob - all warranty will be lost! I am not responsible for any damages!<br/> At the moment you will also loose the water protection - keep that in mind!</p> <p>To get the needed electronics, you have to open your Nuki Fob. Mine was already broken, but I think you can open seperate the top and bottom case when you remove the battery holder (don't blame on me, if this doesn't work - I didn't try that on my own).<br/> Then you have to take the PCB, the battery and the button and put that in the printed "Nuki_Keyholder_Front.stl". Put some M3 screws in screw holes and close the front with "Nuki_Keyholder_Front-Lid.stl".<br/> You may have to sand down the pole in the middle, depending on your key thickness.<br/> Place the keys with "Nuki_Keyholder_Key-Adaptor.stl" (the big ring is intended to be pointing to the back) an the M3 screws.<br/> Last but not least put some M3 square nuts on the back part and screw everything together.</p> <p>Update: Added .step file with slightly optimized measurements and space for a more commonly available (and higher capacity) CR2032.</p>
