Delve into the intricacies of security innovation with this 3D model inspired by the Fichet 787z lock. Noteworthy for its distinctive lever cog-based mechanism, this lock accommodates multiple keys using the same internal components. Explore the nuanced details of this cutting-edge design, perfect for those fascinated by the fusion of technology and security.

 

Note that you will need additional non 3d printable parts to assemble this model. I give a full list of all the parts in the beginning of the assembly video.

The non printable parts are:

  • 5 standard euro cylinder springs
  • 3 larger springs found in the clutch mechanism of thumbturns (diameter is 4.5mm, extended length is 11mm and max compressed length is 4mm) 
  • 2 M3 10mm screws
  • 2 M3 nuts

Also huge thanks to him for helping out with some of the internals and finding the relevant patents. I could have not done it without his help!
