Remix of Barrage insert

I've taken the initiative to remix Fabmaszter models. The original designs were excellent, but I found that the exact fit sometimes led to excessive friction, which in turn caused damage to the box over time.

In my remix, I focused on refining the dimensions to strike the perfect balance between snugness and ease of use. The result is a set of models that effortlessly slide into place without any risk of friction-related wear and tear.

I have not included the extension pieces since I don't have them. You still need to print all the other components from https://www.thingiverse.com/thing:3828519
