Duplicating key from a photo

prusaprinters

<p>To make a copy of a key you need a detailed photo and one measurement to scale the dimensions.</p><p>When taking a photo its best to take it from some distance and then crop it to avoid lens distortion, which will mess with the dimensions.</p><figure class="image image_resized image-style-align-center" style="width:82.38%;"><img src="https://media.printables.com/media/prints/299442/rich_content/3c61d1c1-f04c-4a11-b910-ee5df6ad6bde/zrzut-ekranu-2022-10-20-235545.png#%7B%22uuid%22%3A%2277d9b3ea-5b2a-4bfe-a982-55579b2fe7e1%22%2C%22w%22%3A1870%2C%22h%22%3A904%7D"></figure><p>For the scale, measure long features (eg. lenght of the key) to minimize measurement error.</p><p>Next add your photo as a canvas in Fusion 360, then scale the model entering the previously measured value. After that create a skech and outline the shape of the key and extrude it.</p><figure class="image image_resized image-style-align-left" style="width:47.17%;"><img src="https://media.printables.com/media/prints/299442/rich_content/b2079fb0-ca06-4865-a60f-cd995f489e88/p1.png#%7B%22uuid%22%3A%22f8b0d602-c3cc-4148-89e7-d48277de6276%22%2C%22w%22%3A2131%2C%22h%22%3A1302%7D"></figure><p><img class="image_resized" style="width:47.01%;" src="https://media.printables.com/media/prints/299442/rich_content/6e3a9cb5-b3b9-4c12-ae99-2bdc71d1a205/p2.png#%7B%22uuid%22%3A%22087d3de3-ea3e-4c1e-8b52-8a70252a2040%22%2C%22w%22%3A1863%2C%22h%22%3A1090%7D"></p><p>&nbsp;</p><p><strong>Print instructions:</strong></p><ul><li>Print with maximum wall thickness</li><li>Layers should be parallel to key length to achieve strong print</li><li>Use material that isn't brittle</li></ul><p>&nbsp;</p><p>&nbsp;</p><p>Thanks to this method I was able to reproduce a working copy of lost key to my ebike battery (stl + step avilabile to download)</p><figure class="image image_resized image-style-align-center" style="width:70.89%;"><img src="https://media.printables.com/media/prints/299442/rich_content/5b23cf35-1406-4df0-901e-0cfdf0ca6276/20221021_202215.jpg#%7B%22uuid%22%3A%22b1696203-6934-439e-92a5-ff913ad74e4d%22%2C%22w%22%3A4624%2C%22h%22%3A3468%7D"></figure><p>&nbsp;</p>
