I want to make a unibody, durable version of the above that won't chaffe skin and survives/resists getting distorted even if you try to twist the metal hook loop. Basically I have the above device. I pulled an twisted on the hook and the hook ripped out. I'm looking to create perhaps a metal or other material version of it maybe using caste out of the existing one I have.
What kind of service, website, or machine do I need to find to make a unibody version of the above?
It is okay to make the hook thicker if it gives it more durability. Doesn't have to be unibody as long as the hook stays in place and doesn't twist. And preferably it should not flake or leave bits of it coming off.
If you google TLC Tugger, you will know it's purpose but that leads to a bit of an awkward situation going to the materials lab at university, not being a material student, and asking if I can make this object. Let's just be mature about this, keep it scientific, and not talk about the purpose of the device- just know that it has to be safe medically with skin contact and being lodged in a certain place for many hours at a time.
