Hello again!

Now you can download STL files (Download menu) and print your own sample of my unique mechanism. I am sure nobody can crack it by manipulating the knobs and guessing the correct combination by feeling anything strange. Please watch also my video to help you understand this lock mechanism. Remember: It is in “padlock” just for demo of functionality but it is designed to be placed in safes door or in your residential door. You will be able to use it just i.e. when you will go for holiday or for longer time out. Normally it could be in safe open position for daily use as backup lock.

This 3D model has been printed on Formiga P100 using PA2200 Polyamide in Warsaw University of Technology in Rapid Prototyping Laboratory.
