Solved Where can I get a new y-axis belt?

I have successfully fixed an issue with my y-axis! The belt kept slipping in the coupler/tightener/doohicky-thingy. So I jammed in a piece of plastic to make it stay put.

It works! No more y-axis shift!

However, the fix is wildly janky. I could print and modify latch-thing a bit, but I'd really like to get a belt that's an inch or three longer so I have some play.

Should I just take the belt off and go to the hardware store and hope they have it (or similar enough that it doesn't matter?)

 

You guys rock! Thanks!
