Commercial Look with closed shackle

Here is my latest design of this small padlock with 10 000 combinations inside very secure housing protecting shackle. It is made from steel brass and aluminium. The shackle has 8mm as presented on my video.

IMPORTANT NOTICE: In the final production version the mechanism must be protected against drilling by adding anti-drill discs inside the mechanism covering the internal wheels

Example of possible commercial look.

Donation for further development.

Hello if you think that this lock mechanism is worth further development and you like to see metal model 100% as production one, I need to ask you for donation any funds you can using this link here: https://www.paypal.me/ZbigniewOlejnik

I will not print anymore 3D models (it cost me real money) rather I like to go step further and to make first fully metal production unit for testing and certification. This would be possible only when I will collect some funds from you.

New MOD added to download page

Hello I have just added some modifications to my small padlock design. Those mods are available on download page. Main reason to add this mod is to improve the operation between the Actuator and the Open Close knob. There is much better grip between gears and there is new Dead Bolt and Washer as well. Those are STEP files for CNC rather that for FDM printing because of small tolerances. You can however scale and enlarge this model for PLA printer.

Hello new small padlock for CNC ready for production.

Hello, as you can see in Download section I published today my latest design of small and strong unpickable padlock ready for CNC production. I created it in just 2 days from scratch so now you see how flexible is my mechanism. it could be redesign easily from 3.2 milion to just 10 000 combo, from big to small size. In fact there are infinite variants of this mechanism for safes and other applications. You can download and use those models for private testing purpose but not for any commercial use. There are step for cnc and stl files. I am going now to print SLS this small padlock to test it. There is no clicker yet I am looking for any clever idea how to add it to my mechanism.
