XBOX 360 Wireless controller 18650 battery case

This is a remix of the 18650 case by [m0st1ted](https://www.thingiverse.com/m0st1ted). I redesigned it based on his/her design and rotated the TP4065 module in a way that charging during use is possible, when the plug of the type c cable is long enough. The two separate parts clip in place, so no glue is needed. Use two metal thumbtacks and solder the wires to them. When soldering the wires to the 18650 cell, make sure to keep the time you heat the pads as short as possible (maximum 2 seconds!). This will keep the stress on the battery low. Also use a good soldering iron with a big tip at more than +400°C and tin with flux.
