Hi guys, in this article we will see how to make a very convenient single charger for 18650 cells so that you don’t always have to arrange homemade tools like magnets or things like that to hook into the two poles but use this cute 3D printed design that allows us to charge our cell with a very simple micro-USB cable through a module with the integrated TP4056 inside

But now, as always, get comfortable and let’s see what we need to build it …

- 3D printed piece (so you need a 3D printer
- 20 cm of electrical wire with a minimum of 1A
- Module with integrated TP4056
