Laser cutter camera arm
prusaprinters
<p>I got an OMTech 50W CO2 laser that I needed a way of mounting a camera to. First I got the camera mounted to the lid as I have seen many people do. The lid was a bit to flimsy and the gas springs had an unreliable end point which meant the camera didn't end up in the same position. So I made a spring tensioned camera holder instead.</p><p> </p><h4>Printed parts needed to make this</h4><figure class="table"><table style="border:0px solid #F5F5F5;"><tbody><tr><td style="border:0px solid #F5F5F5;"><ol><li>Base</li><li>CameraBase</li><li>CameraLid</li><li>LeftHolder</li><li>MiddleHolder</li><li>RightHolder</li><li>SpacerX3 </li></ol></td><td style="border:0px solid #F5F5F5;"><figure class="image"><img src="https://media.printables.com/media/prints/283468/rich_content/6adf5667-bc59-4f35-84d8-2a9e0d2e7a7c/sheet1-1.jpg#%7B%22uuid%22%3A%2250d35de5-cae7-47f6-833a-e6cbaf9bccab%22%2C%22w%22%3A2175%2C%22h%22%3A1883%7D"></figure></td></tr></tbody></table></figure><p> </p><h4>Other parts needed</h4><ul><li>13 x Lock Nut DIN 985 M3</li><li>2 x Hex Nut DIN 934 M3</li><li>8 x Swuare Nut Din 562 M3</li><li>4 x Screw DIN 912 8 mm M3</li><li>8 x Screw DIN 912 12 mm M3</li><li>4 x Screw DIN 912 16 mm M3</li><li>2 x Screw DIN 912 22 mm M3</li><li>4 x Screw DIN 912 30 mm M3</li><li>3 x Screw DIN 912 45 mm M3</li><li>2 x Laser Cut Acrylic Arms</li><li>1 x Lightburn Official Camera</li><li>4 x Springs 6 x 20 mm</li></ul><p> </p><h4>Assembly instructions</h4><figure class="table"><table><tbody><tr><td><figure class="image"><img src="https://media.printables.com/media/prints/283468/rich_content/191111ce-ac79-491e-846f-2f183fc6cf21/img_5605.jpg#%7B%22uuid%22%3A%22271cf7f8-eb9b-49f2-9c12-f929ba01c91c%22%2C%22w%22%3A1920%2C%22h%22%3A1920%7D"></figure></td><td><figure class="image"><img src="https://media.printables.com/media/prints/283468/rich_content/01ce9643-0399-44c6-8bdc-50660149c61d/img_5606.jpg#%7B%22uuid%22%3A%227624fd02-2b9a-45b5-a008-757ddd827f3a%22%2C%22w%22%3A1920%2C%22h%22%3A1920%7D"></figure></td><td>Start by inserting all the square nuts.
