battery 18650 welding jig
Description
Even after a few tries this file is not a perfect fit (for 7 batteries). I had to melt a shallow little groove at the ends, to widen it a hair. But I'm getting different shrinkage from ABS, PLA and some unknown scrap filament. This version is PLA, about 22 grams (no raft). The neodymium magnets are too strong for this. Their magnetism is even transferred to the battery case and that can twist the next one in line... North to South pole stuff..... and other unnecessary difficulties, like getting them flush in their sockets, and super-gluing them in place. But if you want them, they're probably advertised as 5/6" D x 1/8" inch thick, but are thinner. I will remove these and glue some magnetic tape across the back when I find some. It doesn't take much to hold a battery upright. If your software imports a microscopic file use the Metric version.
