I am woking on making solar panel mounts for the roof rack of my nissan xterra from TPU, since it can take a beating. Does any one have any experience with 3d-printed TPU threads? And how much stress before it can take before a bolt rips out? Also should i use teflon thread seal so the a bolt won’t come loose?

    Use metal fasteners. Plastic fasteners are too weak for your application. The shear and tensile strength of plastic is quite low.
