Summary

A friend of mine give me a dozen sup-air ball bunkers as a gift, but they didn't have there air caps, so I made my own design and printed them and they work perfectly, This are for 24mm diameter threads

I printed mine with PEGT because it is what I had but I guess that PLA and ABS will works as well
