A spacer to use flat top 18650 batteries in the Emisar D18, without taking the polarity protection rings off. Hard to get high quality button top 18650 batteries where I live so I designed this.

Takes 10mm diameter cylindrical spacers, taller than 2mm. I used some spare neodymium magnets but brass or copper spacers would be ideal for a reduced electrical resistance.

FreeCAD file allows customization for smaller spacer diameters, 10mm is the biggest that works without being too fragile.
