I wanted some custom valve caps to protect my car tyre valves. I had used some metal ones before but they got welded to the valve so I wanted something plastic to prevent that but also hex headed so that if it did get stuck I could get a spanner on it. As they are plastic they could be cut or melted off if needs be, protecting the valve itself.
I've modelled in the threads and the ones I printed fit perfectly but dependant on your machine you may find they print tight. I've modelled at the max loose tolerance of the valve standard so hopefully this should be enough.
My setup is a Prusa MK3S+ at home and I have 3 at work. Across all of them they came out the same. I printed at 0.2mm height as this allows the threads to be self supporting. 0.3mm should work fine but it may just cause the threads to be a little tighter as they may deform slightly.
If you don't have a 3D printer, you can buy this part from my website:
