LED light torch

Simple LED light encasement for CR2032 battery and one diode. Light is turned ON/OFF by sliding the battery - no soldering required.
You can use it as it is in small lantern or intergrate the battery holder into your own design.

Printed parts Sample printed with 0.35mm noozle, 0.1mm thick layers. As walls are quite thin it is printed with 1 outline only and 66% of infill. Presumably 0.5mm noozle with 0.2mm thick layer can be used too, but not tested yet. Thicker walls makes switching harder.
Assembly When printed insert the LED wires in propper holes (CATHODE [-] in the center, ANODE [+] on side) and bend them so they hold inside firmly.
Operation Insert CR2032 3V battery and slide it from side to side to turn the light ON and OFF.
Required items 1 Printed encasement from STL file 1 LED diode for 3V of any colour (5V can be used too but light intensity will suffer) 1 CR2032 battery
