<p>Articulating light mount that utilizes the business end of a dollar store flashlight.</p> <p><strong>Supplies</strong></p> <ul> <li>Dollar store / gas station / <a href="https://www.walmart.com/ip/Ozark-Trail-Mini-Flashlight-in-Assorted-Colors/34350005">Walmart</a> flashlight.<em>(Check that drawer in your kitchen, I had two)</em> </li> <li>Resistor depending on power supply and needs. </li> <li>Some thin wire, something you can route in the unused rail slot behind the psu </li> </ul> <p><strong>Assembly</strong></p> <ol> <li>Disassemble the flashlight and remove the head</li> <li>Solder wires to the head of the flashlight as shown below (fig1), the inner ring should be the cathod (+) and the outer ring should be the anode (-) </li> <li>Pass the wires through the cap</li> <li>Insert the bolt into the head, this also should be quite snug to prevent it from spinning, use the nut to draw in if needed</li> <li>Fit the LEDs into the head</li> <li>Press the cap into the head</li> <li>Assemble the rest of the arms as shown below(fig 2)</li> <li>Slide the assembly onto the rail</li> <li>Wire as needed<br/> <strong>*Important:</strong> there is no resistor in the head of the flashlight be sure to add as needed depending on your power supply.

PLA is just fine the light gives off no heat.</p> <p><strong>Post-Printing</strong><br/> I left the fit between the cap and the head rather tight. Ensure that you can remove the cap, lightly sand if needed.</p>
