Hi, I've recently tried out modded materials and noticed that Rocket Witch made Nylon 66. Nylon 66 is fairly lackluster as a plain form but in a lot of usage cases with modern plastics, especially Nylon 6 and 66 there's usually a significant amount of glass fiber (Such as PA66GF30, 30 = 30%, pick up a power tool and look for the markings on the outside) or in more rare cases long strand carbon fiber that's added. From my understanding the functional properties of it is somewhere close to something like 6061 or 7005 Aluminum in some cases while keeping the part exceptionally light. There are some cases of tools where a PA66CF>30+ part is used in place of a metallic one as the part is used in a moving assembly where it reciprocates back and forth rapidly.
This is just a terrible, terrible first time hack job I made off looking at material data sheets and using the scaling on the ratio vs normal Nylon 66. I think someone who is much better than me at reading the datasheets can probably adjust these values so they look sane(r)?
