BBC microbit v1 battery pack holder (not suitable for new microbit v2)

I have created multipurpose battery pack holder for BBC microbit. I have spent lots of time perfecting it. It can stand on its own, be clipped on lanyard or with use of velcro strap used as wearable. Now i am releasing it out in the wild. If you like it and want to support me please buy me a beer here :)
