Improve the triggers on a video games controller

I've always found the design of the PS3 controller a bit annoying as the trigger buttons sloped inwards and weren't really "triggers". I had bought special clip on triggers that were OK but kept coming off and I eventually lost all but one.

When I received my first order I had a different project in mind (which I have yet to start) but the thought occurred to me to try it on the controller. It was surprisingly easy to get a nice clean, symmetrical and (most importantly) comfortable shape and have a good smooth finish. After the first blue triggers were cured. I was so impressed that I decided to do the other controller in red.
