So revisionfive/iamthatcat asked me to do an exploded view of my Nano Jolt's trigger. You ask, and you shall receive! Hopefully this post explains clearly how I do mine:

How I did mine was really simple.
Step 1: Find spring.
Step 2: Wedge spring under trigger.
Step 3: You are done!
Better pic
I did this originally as a temporary hold until I found an adequate piece of plastic, however it hasn't had any flaws yet!
This method is also MUCH easier than finding and cutting a plastic rest.
Exploded view: trigger, pin, and spring
Spring close up
The spring I used was from a longer spring. I just cut a small segment off, and used that. It doesn't have to be extraordinarily strong, because mine isn't.
(Sorry for the bad lighting in the last two pics.)
Here's a vid that will hopefully explain all of this:
Hopefully, I explained this so that it can be replicated. Its so simple, I'm not sure how one would be unable to understand!
