AA Battery holder Sleeve

Those cheep single AA battery holders always split on me after a few months so I designed a simple sleeve to slide over them to hold the battery in place, help slow down the splitting and to hold a battery in a split holder.

I have shown it in use here around my Joule Thief driven night torch that uses flat batteries to drive a blue LED often for months, non stop.

Instructions

I printer with my Wanhao D4S, 20% infill but to be honest most setting should work just fine. I guess (but havent tried yet) that an equivalent AAA sleeve could be printed by reducing the design by some percentage.
