Sena SMH10r battery replacement

prusaprinters

<p>I made this replacement battery for my Sena SMH10r bluetooth headset, because it was purchased 5 years ago, and apparently, Sena changed the shape of the connector, and the new replacement battery is no longer compatible with older headsets. Nonetheless, this costed maybe 3 Euros, while the official replacement battery is around 50 euros.</p> <p>Maybe you have to play a little with the connector scale when slicing, I had to print it at 110% with a 0.6 nozzle (single line wall) but now it fits perfectly</p> <p>With the battery case I was more lucky and printed with standard settings it fits perfectly in the original battery holder.</p> <p>The connector has no holes for the pins, because they are too tiny to be printed, so I made the holes with my Dremel and a 0.5mm bit, and used a steel needle for the pins</p> <p>The battery box bottom and top parts were glued together with superglue and filled with silicon so it's 100% waterproof.</p> <p>The battery is a generic 3.7 battery, I bought 5 on amazon for 10 euros</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>100%</p></div> <p><strong>Filament:</strong> Generic PLA+ White</p> </p></p></p> Category: Automotive
