I am considering new setup 7 wheels but only 0-9 (ten numbers) on each knob. This padlock have 10 000 000 unique combinations. The body size is 60mm width x 35mm depth and 100 mm high. It is now ready for production. I need your support to start first metal version. Please donate any funds counts.
Here is how the heart on this mechanism would look like:
