Battery adapters and dummy

thingiverse

I am collecting Battery Dummies for use as adapters, allowing me to insert a Mignon (AA) cell into a Mono (D) Dummy with ease. These dummies are my go-to solution when I need to power devices that require Baby cells, eliminating the need for a charger on rechargeable batteries. To function as an adapter, you simply slide a small metal wire through the hole at the top. This ingenious design makes it easy to get started right away.
