Shadowrun-themed knob for Secret Lock Book

I decided to try to create a new knob for the secret lock book. It's not quite right - I didn't manage to create the snap-in section to mate with the gear - but if you intend to glue it together, it should work out fine.

Update: new version included, with the snap-in section due to the generosity of mrhers2 who brought the lock into the book in the first place.
