100W LED flashlight 18650

This flashlight uses a 100W diode cooled with a PC heat sink (stock lga1150 and similar). Powered by used sanyo 18650 cells. Power regulation by means of a potentiometer.
In the near future I will draw up a list of necessary parts and instructions
Print with nozzle 0.8mm (0.32mm layer height) on ender 3. The casing is very hard and strong. May require delicate sawing on multimetr and power switch. The rear flap is mounted on screws from a pc fan.
