9V Battery Cap

thingiverse

My remake of some similar designs here. However, I found that those I discovered elsewhere either never fit quite right or the rings connecting to the battery would snap off, forcing me to dig it out from the battery. What I did differently was create this with flex filament. Microcenter has its own brand of flex, which is significantly firmer than Nijaflex and works exceptionally well in this application. As a musician who plays in a band, I need to have 9V batteries readily available in my gig bag for my guitars and stomp boxes. These keep the batteries from shorting out, eliminating the need to use cardboard and tape. I tend to print a batch at once and simply store them in a zip lock in my battery drawer.
