Actually I am completely surprised by the strength of the 10K. You can’t break this with your fingers but I imagine it is brittle so that any impact will be an issue. I know just don’t hit it right?
Most of the time barbs similar to this are PP or Nylon. So the tough maybe great. I will print some and test.
It is just the long term that frightens me. Would you still give a light UV dusting or leave it if it is indoors. Does the long term UV exposure make even the Tough resin brittle?
