Hello, i need some help with a recommendation for nylon filament for an end use functional part im making. The part is a latch for a door. The environment will be mostly very cold temperatures (ie outdoors in winter) I cant use a reinforced filament, as it needs to have a small amount of flex at these temperatures. I have cold tested a few parts i made over a decade ago in taulmans bridge nylon and it seems to be the right material for the job. unfortunately it seems its no longer available. Is there something on the market that would have similar performance? Tpu 95 is way too flexible.I have tried tpu for ams and it is perfect in every way for this part, except at freezing temperatures, if attempting to flex even just a little, the part snaps.
