Maximized for the Replicator
UPDATE: I added plates for the replicator, you need one of each plate to have a full lock.
Pin 1 is the closest to the key opening, Pin 5 is the furthest
Print 5 copies of the driver pin
I haven't printed this yet, so beware the tolerances might need some tweaking.
iworkinpixels promises to make an openscad file that will make parametric keys and pins for custom locks... pester him
