2023 Solis 59P cubby hole in floor - document safe

[Road2nowhere]

I own a 2023 Solis 59PX. It has a cubby hole in the floor next to the receptacle for the table leg behind the driver. The cubby has a lid but isn’t secure. I currently have the rigs manuals tucked inside it.
Has anyone found a safe that would fit and bolt into this cubby?
I’d prefer a keyed safe that is flush mounted with the floor level.
If not a commercial safe… has anyone installed piano hinge and a lock… any problems foreseen?

Hi Road2nowhere,
Amazon has this one which comes in three sizes:
Amazon Basics Steel Security Safe and Lock Box with Electronic Keypad
and this one is even smaller:
Bonsaii Safe Box
The big thing is that it not be visible for passers-by.
What is the net size of your enclosure?
Thanks, Eagle5
