Hello, thanks to one of the Polish 3D printing Company I make step forward towards presenting first 3D model of my new lock mechanism Polish Combination Lock. It is inside padlock just to show how it works. This first printed worldwide model is fully functional and working fine, printed just on FDM technology. Next model will be printed on SLS and then I will make video to present and explain all details to you based on full 3D model and real presentation. This padlock has 3.2 milion unique combinations! Of course in the end this mechanism will be mounted in safe doors and other high security places, padlock is just as an example to show you the idea how my unique locking mechanism works.
