LTT Commuter Backpack Strap Clip

Why?

Because mine clip also broke. https://www.reddit.com/r/LinusTechTips/comments/1iuuew2/commuter_backpack_strap_clip_broke/
Support does not currently offer replacement.

Since you can't get the strap out of the metal thing (you can try, but be careful not to damage it) I had to design this solution. You just jam it inside and it holds!

The clip may be too tight - that's how it's supposed to be. 

I've been testing it for days, this is fifth iteration and it works the best! (If you still find it too tight, print the “not so tight” version.
