Breitling Case Back opener

Tool to open the caseback of a Breilting Watch, This was made referring to a Colt 41MM, I believe there are different sizes but as long as there is 15 edges, this could be scaled accordingly?

i printed on cura default for high quality, seems to be strong enough, on my machine i had it sized to 100.5% and it snapped nicely on the back of the case.
