Another 18650 Charger Station <h2>Summary :</h2> Another 4-bay 18650 battery charger station.<br> Inspired by this great <a href="https://www.thingiverse.com/thing:2818608">thing</a> by <a href="https://www.thingiverse.com/memisis">memesis</a>... with some modifications. <h2>Modifications :</h2> <ul> <li>Rather than taking them apart, the 18650 battery-holders are left as they are and are incorporated/glued into the charger <li>Merged the 3 panels : button-, voltmeter- and switch-panels and power-inlet into 1 panel. <li>Smaller on/off <a href="https://www.amazon.com/Muscccm-Lighted-Latching-Household-Appliances/dp/B07C7RXFT1/ref=sr_1_13?ie=UTF8&qid=1532338100&sr=8-13&keywords=mimoo">switch</a> (resulting in a reduced height of the station). <li>Inner frame and cover can be assembled (glued) and then all wiring and soldering can easily be carried out from below. Afterwards the outer shell covers the wiring. <li>Wiring scheme : see the original design <a href="https://www.thingiverse.com/thing:2818608">here</a> <li>Thinner walls to reduce filament use (by about 15% - 600 cm.). Reduced printing time. <li>All 3 parts print without supports </ul> <h2>Hardware : </h2> <ul> <li>TP4056 Lipo battery charging modules (<a href="https://www.amazon.com/McIgIcM-Battery-Charging-Charger-lithium/dp/B06XXYTRGK/ref=sr_1_1_sspa?ie=UTF8&qid=1532350224&sr=8-1-spons&keywords=tp4056&psc=1">tp4056</a>) <li>LED Lighted Rocker Switch, DC 12V 20A On/OFF (<a href="https://www.amazon.com/Muscccm-Lighted-Latching-Household-Appliances/dp/B07C7RXFT1/ref=sr_1_13?ie=UTF8&qid=1532338100&sr=8-13&keywords=mimoo">switch</a>) <li>Mini voltmeter Yellow (<a href="https://www.amazon.fr/gp/product/B00AW4DG1Y/ref=oh_aui_search_detailpage?ie=UTF8&psc=1">voltmeter</a>) <li>Momentary SPST NO Red Round Cap Push Button Switch AC 6A/125V 3A/250V (<a href="https://www.amazon.com/SODIAL-Momentary-Round-Button-Switch/dp/B00F4MGQU2/ref=sr_1_13?s=hi&ie=UTF8&qid=1532361911&sr=1-13&keywords=sodial+button">buttons</a>) <li>DC-022 5.5-2.1mm Round Hole Screw Nut DC Power Socket ROHS Internal Diameter 5.5mm (<a href="https://www.amazon.com/ILS-pieces-5-5-2-1mm-Internal-Diameter/dp/B0769K5J74/ref=sr_1_1?s=hi&ie=UTF8&qid=1532362175&sr=1-1&keywords=dc-022">power socket</a>° <li>Black Battery Storage Box Case Holder for 3.7V18650x1 Batteries (<a href="https://www.amazon.com/Battery-Storage-Holder-3-7V18650x1-Batteries/dp/B076RKM9QP/ref=sr_1_fkmr0_1?s=hi&ie=UTF8&qid=1532362315&sr=1-1-fkmr0&keywords=togoo+3.7V18650x1">battery holder</a>) </ul> <h2>INSTRUCTIONS :</h2> <ul> <li>Print all 3 parts <li>Assemble/glue cover and inner frame <li>Mount buttons, switch and mini-voltmeter <li>Before you glue the battery holders into the inner frame : re-route the wires so they come out the bottom (see pics) <li>Solder everything and test <li>Evt. glue wires in place on the underside of the inner frame <li>Glue exterior shell over the inner frame </ul>
