Battery holder 18650 x1-x5 with TP4056 chargers

thingiverse

I have the N in 1 18650 TP4056 Charger from YXC https://www.thingiverse.com/thing:2847497/files, by the way, a very nice design, a bit redesigned What I personally didn't like was that the minus pole cable must be routed outside, and that the pole contact only consisted of a piece of wire. I led the minus pole cable inside so that it is no longer visible and provided the pole contacts with 0.1x8mm nickel strips, and the soldering points are then covered with a cover. The TP4056 charger has also been given a cover. There are version of x1-x5 chargers. The TP4056 board can be up to 28mm long. Note: Insert the cable into the minus pole from above, this is easier as soon as it has passed the curve. You can find the 21700 battery version at: https://www.thingiverse.com/thing:5137176 Update: I also attached pictures of my 4-way charger, with a connection for a power supply with 5 volts 10A.
