Button Cell Conversion
thingiverse
My kids rapidly depleted the button cell battery in their toy, prompting me to find a more cost-effective solution. I created a 3V AAA pack that securely attaches to the button cell holder via snap-on screws. Using 30 gauge wire, I established the necessary connections within the pack, and designed it entirely using Solidworks; printing it on a modified Anet A8 in white ABS plastic. Just three days after assembling the new battery pack, it has withstood several drops without any parts coming loose or breaking off.
