for this I used jayo light blue but I think any light blue pla is good, it depends on which version of Jaws you have, perhaps on the premium a darker light blue could also be good, but the important thing is to use a very bright red, I tried very pla red and most are not suitable, you need a blood red, even for the red I used jayo

thanks for the info, much appreciated! I will post pictures when I print this.

oh yes thanks, I'm happy to see your result and your advice to improve the models
