These adapters enable users to power their devices with a single 18650 lithium-ion cell in place of two standard alkaline D-Cells batteries. After printing, simply thread suitable copper wire through the carefully designed slots to establish reliable contacts. I recommend using solid 10 gauge wire, which is commonly used for household electrical circuits.
