9V Battery Cap

My remake of some similar designs here.

However, I found that those I found here either never fit quite right, or the rings, which connect to the battery would snap off, and I'd have to dig it off the battery.

What I did a little different was to make this with flex filament. Microcenter has their own brand of flex, which is much firmer than Nijaflex, and works really well in this application.

I play in a band, and need to have 9V batteries in my gig bag for my guitars and stomp boxes
