LR to AA battery adapter

thingiverse

Utilize this adapter when recharging LR rechargeable batteries in a common AA charger. To ensure accuracy, I measured both LR and AA cells using digital calipers before creating a model in SketchUp. Following the design, I sliced it with Slic3r software for 3D printing on a Printrbot Simple, then added an M3 20mm screw to secure the part with a torx head screw available from my collection.
