How to make a mask for hashcat?

Question

linux

Hello. Help compose a mask for hashcat.
I know for sure that the beginning of the password is, for example, 12word*/.
And then there are only numbers and letters (different case); the length of the unknown part is from 3 to 12 characters.
Thanks in advance!
