AAA to AA battery adapter

thingiverse

Here is the rewritten text: 1. This adapter converts AAA batteries to AA battery size. 2. Since my wireless mouse requires two AA batteries, I switched to AAA to reduce weight. 3. The adapter has been specifically designed for lightweight use. 4. It prints both positive and negative terminals; the large hole on the negative side does not require any processing, but the small hole on the positive side needs a screw from your toolbox to create contact points.
