Label your cables: A B X Y Z 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Colorify and resize them according to your needs (sorry as a set_ I didn't upload each label seperataly).

Default size is 8mm out-to-out (suitable for 4mm cables).

No supports needed for small sizes but if you enlarge them too much some chartacters may overhang during print.

I highlighted inside of the characters with pen/pencil after print for easy reading.
