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.
Yeah the idea to 3d print solar panel mounts with printed threads is probly a bad idea.
