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. These keep the batteries from shorting out, and me having to used cardboard and tape. I tend to print a pile at a clip, and just keep them in a zip lock in my battery drawer.

I also included a version with holes in them so you can test them with a battery tester, without having to take to caps off.

Enjoy.
