Universal key for electric boxes (fuse boxes)

No supports needed, and it's only about 5g of filament. Less then 1h of print. This should be the universal key for electric boxes. I put the example of the lock (for you to know which kind of locks should this key open). Originally I made it for business I am working at, because our original key got lost. I tested this one and it works, but still is prone to breaking if the force is too strong - so I advice that be gentle when using it - or try to use ABS or PETG, maybe that would help with sturdiness. Please post photos and opinions about my model. Thanks so much in advance.
