A remix from Buck Converter Box (LM2596) by LDG92, open ends without rail mount.

Customized specifically for CR10S Pro.

The original mount box design is already snap fit/screw free, I just added two mount holes for 6x2mm magnet , so that it's much easier to mount on any metal surface without glue or double-side tape.

!! DO NOT insert magnet with heat like inserting the screw mount, the magnet will lose its magnetic, I learned it the hard way:(

Insert and glue the magnet, I specifically enlarged the hole a little bit for easy insertion.
