Huawei P20 pro Phone-Camera Mount for analog microscopes

<p>I sometimes have to analyze small parts for my work, and due to the pandemic caused “work from home” situation, I don't have access to the digital microscope in the office.</p><p>At least I have an analog microscope at home, but I was not able to share my findings, because I was not able to make pictures of it.</p><p>I started to try to hold my phone camera over the ocular by hand, but it was hard to get a reasonable picture.</p><p>So I designed this fixture, to always have the camera lens of my phone well aligned to the ocular of the microscope. The results are always satisfying.</p><p>&nbsp;</p><p>The ocular adapter has oversized holes for the mounting bolts, and also for the phone-plate. This allows alignment adjustments between the phone-camera lens and the ocular of the microscope, if need be.</p><figure class="image image_resized" style="width:74.42%;"><img src="https://media.printables.com/media/prints/175057/rich_content/56a6f01f-5fc0-4700-bb15-33b024ed2ddf/hua-p20p_mic_d.jpg#%7B%22uuid%22%3A%229bb1db03-c53e-4276-b905-3600e1d52cf8%22%2C%22w%22%3A1080%2C%22h%22%3A810%7D"></figure><p>For assembly you will need:</p><ul><li>4x Bolts M3 x 10 (3x for the ocular adapter, 1x for the clamp)</li><li>4x Nuts M3 A/F 5.5 (standard) (3x for the ocular adapter, 1x for the clamp)</li><li>3x washer DIN9021 (oversized outer diameter)</li></ul><p>The ocular of my microscope has an outer diameter of 37mm, and is approx. 30mm long. This might be not standard so I added the file for the ocular adapter as STEP, so you can adjust or redesign it according your needs.</p><p>Anyhow, the ocular adapter requires support for printing.</p>
