just practicing to build boxes to hold the dna 20 .laaaater .had the z max and got inspired by breaktrue I wanted a case for the 18650 battery as small as possible with all the goodies in it. used circuit board one sided material for the " skeleton " and carbon fiber clamb shell .the build in charger works great. the z max board sits in a little fiberglass tray and is not glued to mod . so far works great !!!
