This is a simple clip for holding t-nuts in place in 3030 extrusion that I made as an assembly aid. This was designed for and tested in Misumi HFS6-3030 extrusion. Simply press the clips into the slot where needed or slide in from an end. They should be a snug fit but move without too much effort. I think I will be making a 2020 version soon.
Update 1-25-2018:
I had tried making a similar thing for 2020 extrusion but the smaller dims + tolerances didn't work well. Maybe something like this could still be done with a flexible, but I doubt I will try that unless I find myself working with a lot of 2020.
