Utility meter Box Lock

This is a direct replacement for the door lock on some outdoor UK Utility Cupboard doors.
A 'key' with a triangular hole is used to open the door.
The original triangular male portion of the lock, on the door, broke off due to wear & tear & also age.
Due to it being printed 'on end', I recommend a raft and supports.
It takes around 20 minutes to print at the given settings.
