AA Battery Holder (lockable) for Rechargeables

thingiverse

I designed a rechargeable battery holder that fits snugly in place, holding one battery at a time until all are loaded or empty. Simply rotate the top part to secure each battery individually, ensuring they won't fall out or get lost. For added peace of mind, I included an intermediate position that locks all batteries inside when fully charged or depleted. This way, you can store them safely without worrying about uncontrolled movement. 1 M3 screw is required for assembly. The design was inspired by my son's high-energy RC car, which demands a constant supply of spare batteries to avoid costly mishaps. A single missing battery can cause serious problems!
