Battery cases for 18650 and 14500

thingiverse

I completely remade the design from Alyohich's brilliant creations on Thingiverse. You'll find custom battery cases for 186500 and 14500 batteries, similar to standard AA batteries. I've used LitoKala's high-quality 18650 batteries with built-in protection boards. These batteries measure 69.5 x 19 mm in size, while the 14500 batteries are 51 x 14 mm. If you need a case for regular 18650 batteries measuring 18 x 65 mm, simply ask me for the model or add your own soft padding from foam or rubber to prevent rattling. Additionally, there's a 1 mm vertical gap in both AA and 18650 cases for a soft gasket. To boost capacity, I've added an extender inspired by Dave 312's innovative design on Thingiverse. If you need custom cases for other types or sizes of cylindrical batteries, get familiar with Fusion 360, and I'll provide you with a parametrical model that's easy to modify. Just change the parameters and remake the thread to fit your needs!
