This is a lockable drawer. I have used a lock cylinder from an old door. This type of lock cylinder is very common in all types of door locks.
The lock dylinder dimensions are: 60 mm long x 33 mm high x 17 mm wide (10 mm at the top)
The base and drawer dimensions are: 102 mm long x 123 mm wide x 42 mm high
The storage dimensions are: 97 mm long x 97 mm wide x 38 mm high
The best way to print the base is VERTICALLY and the drawer HORIZONTALLY.
