<p>Dremel 7700 Battery Pack Charge Dock. To be used with a NiMh 6S intelligent charger.</p> <p>I upgraded the worn AA 0.7A NiCd cells in the original battery pack to AA 2.6Ah NiMh cells. There are 6 cells in the battery pack and after upgrading I needed a new charger as the supplied one only does NiCd charging. I made a dock station which will mate up to any charger.</p> <p>I used a cheap Maverick 2S-6S NiMh Charger that comes supplied with RC cars. I then wired the Dock station with a Tamiya Battery Socket Connector to connect to the charger's Tamiya Battery Plug.</p> <p>Apart from the 2 parts of the print you only need 4 x AAA 5mm Battery Spring connectors, a Tamiya Battery Socket Connector with some wire and 4 x 10mm M3 self tapper screws.</p> <p>Assemble as in the picture with red cable on 1 spring connector, black on another and the remaining 2 connectors soldered together as show in photo (This is to bridge the 2 x 3.6v parts of the battery pack together.</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Creality</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>Ender 3 Pro</p></div> <p><strong>Rafts:</strong></p> <p>No</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>Yes</p></div> <p><strong>Resolution:</strong></p> <p>0.2</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>40%</p></div> <p><strong>Filament:</strong> Eeyone PLA Black</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>Dremel 7700 Battery Pack Charge Dock.
