I designed this for my old Interact Dreamcast light gun. The trigger broke back in the early 2000s and has been collecting dust ever since. I recently started getting back into CAD again so I figured this would be a good first project for me. After about 45 minutes of work I got the design down and printed it up.

It works well for me. I did use some super lube I had left over from reframing some old N64 controllers. The trigger slides against other plastic so I wanted to make sure the trigger slid back to the default position.
