bricard style interior key

I wanted to print an interior key for my doors, but all the original keys were lost one way or the other. i didnt find any model for this keyhole, so i designed my own.


The longer version (original measurement from the site) was too long for my keyhole, prohibiting me from turning the lock, so i cut down the excess leaving 1 cm left of the Z, i could then rotate the lock :^)

A year and 4 months later: rephrasing and organizing the text, and key number 29 was added, it was a quick and dirty design, it might not be functional.
