Flashlight 18650 with charger TP4056.

It is a flashlight that gives a moderate light so the battery lasts a long time. It incorporates a TP4056 (with micro USB) that controls the charge and discharge of the 18650 battery. It uses 5v led strips. In the future I will create pieces to change them for high intensity DIP LEDs. The flashlight has two variants; with a single led or with two leds in parallel. I recommend the one with 2 leds because the one with 1 led projects a very dim light. As "there is nothing written about taste..." I have incorporated the files of both options :-) The bulb piece fits into the body of the flashlight, guiding us through a couple of points. Then the bulb is turned a quarter turn towards the switch and the assembly is attached and fixed. If the joint is too loose, you can put a small screw in a hole in the bulb. The ".stl" parts are arranged so that no brackets are needed. The internal cone of the spotlight reflects light better when printed on white material. The "glass" of the spotlight I cut out of the top cover of a CD or DVD case. Watch out for the water. The flashlight is not liquid-tight because it has ventilation holes to dissipate the heat from the charger, as well as a window to allow you to see the charging and end-of-charge lights. WARNING Do not use this type of battery without a suitable controller, it is DANGEROUS. They need a controller to prevent them from overcharging and overdischarging. It is as bad to charge them too much as it is to empty them too much. In the case of this flashlight we use the TP4056 that in addition to the charge control, incorporates an over-discharge control.
