Build a Acrylic Case and Lock Engager Based on the Physical Lock you have at home

Since i wanted the lock to be customisable and not dependent on any specific lock hardware
I created a generic Acrylic Base but the lock Engager and position of the Servo is dependent on the type of Lock you are using at home. will give some guidelines to build that below
