Battery Holder for 4s 26650 Pack

This is a battery holder for a 4s pack of 26650 size cells. I made this primarily for powering my Sound Devices MixPre-D, but you could use it for other stuff too. It consists of 3 parts.... a case, an inner support that holds the threaded inserts, and a cap to mount the switch, voltmeter, and power connector.

If you don't want to use the Hirose connector, the hole will fit a coaxial power connector just fine. I've included an STL for the cap that has no cutouts, so you can make your own.
