ALICE backpack strap clip replacement

This part is to replace the clip in the shoulder strap of the military ALICE backpack.
When finding these surplus backpacks these clips are usually broken already.
The extra opening in the clip was made so it can easily be attached without the need to remove the snapbutton.

1. Print the clip
2. Remove some stitching from the strap so the clip comes loose
3. Break away the old broken clip
4. Slide in the new printed clip through the slanted opening
5. Replace some stitching
6. Done
