About this 3D model

I replaced 4xAA alakaline batteries with AC/DC 6V adapter. The smart lock power consuption was too high and the alkaline batteries didn´t last so long (I have safety door which have three locking points and it has probably huge impact on battery lifespan… The model is not smooth as you can see on photos. You will probably need to use knife and cut a little part of battery adapter but its easy modification and all is hidden inside the smart lock. I designed this adapter 5 years ago…. BTW: You will need screws and spring as you can see on photos
