Mod Box with a Cuboid mini Mainboard

thingiverse

I had an old Cuboid mini Mainboard, which didn´t charge via USB anymore. So I decided to build a enclosure with 6 18650 batteries. Wired in parallel. Base is a cheap 510 from ebay. The flex battery holders are smaller than the originals with smaller walls. Mainboard is glued in. While vaping at 40W it doesn´t get warm. Because it´s so heavy and voluminous, I only use it at home. With a 510 Adapter to USB, you can also use it as Powerbank.
