9 LED Flashlight 18650 Cell Adapter

EDIT: So after some time the LEDs in both of my Flashlights start to die, USE AT OWN RISK.

Well, this Crappy 9 LED Flashlights with 3 AAA Cells, though it would be useless garbage!

Buuuuut, i get my hands on some old 18650 cells, so 3,6-4,2v with a rechargeable battery and not only max. 3,6v with 3 AAA NiMH cells.
Actual you dont even need this part, to get the 18650cell in this flashlight.
It simply fits in it better and dont wiggle around with it.

Aaaand i wanted to use my printer again for somthing.... im short on free time.:S
