LED light torch
by thorgal, published
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.

<b>Printed parts</b> 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.
<b>Assembly</b> When printed insert the LED wires in propper holes (CATHODE [-] in the center, ANODE [+] on side) and bend them so they hold inside firmly.
<b>Operation</b> Insert CR2032 3V battery and slide it from side to side to turn the light ON and OFF.
<b>Required items</b> 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
