right before I headed for my trip to Italy, i realized that i am packing a lot of things just for my ecig and i needed something small and versatile. I use a mech mod for my everyday and with that i would need to carry extra batteries and charger. after scouring the net only to find that the box mods are still so large and anything i wanted small that would fit a 18650 battery is well over $100, i decided to make my own. I compacted everything into 1 small 80x45x25 box, simular size to a coupler mini.
Please be kind. this is my first thing i ever designed and printed, i am very proud of this item and i know it still needs some fine tuning.
wired up the box mod. everything fit as i wanted. i uploaded more pictures of the wired box.
this is a single 18650 box mod unregulated with a tp4056 lipo charger module.
