Plasma trigger knob

I hired some one here to create this for my Chinese plasma cutter. They didnt see the value of offering it to the masses.

You can buy a plasma cutter from Ebay. Yet they dont offer replacement triggers for their cheap design. Drop the handle and SNAP! There goes the functionality of the tool. The place where the pin goes was re-enforced.

Let me know what you think. As I am only a end user.
