I was looking for a M16x1.5 petcock for my Aliexpress fuel tank (I'm building a custom scrambler and the petcock that came with the tank is touching the frame, so I needed a more compact petcock).
I found a NSR125 petcock which was perfect for my needs, but it didn't come with the original knob (I think the original one is integrated in some body panel). I quickly designed and printed a little lever. It takes less than 10 minutes to print it and it works perfectly.
You need a M5x10 to secure the knob to the petcock. Print with the flat side facing down.
