Just to share with the 3D printing community a simple hack for Li-Ion Charger.
The battery charger for my LED torchlight was broken and thrown away few months back. I was not able to charge the battery.(It was a bit smaller than 18650 size.)

I was too eager to re-print slowly, so replace it with a small wooden block that I shave to size with a pen knife. Coiled the wire around the wooden piece and shovel it into the hole. Done.
Tested charging to be working. Another project done. 😏
