Otoscope Mount for Prusa Mini Nozzle Monitoring

prusaprinters

<p><strong>OOPS!</strong> My original design was for a slightly improperly built Prusa Mini and my heat block, heat break, and nozzle all sat lower than they should have. <strong>I've redesigned the Otoscope mount part to be 2mm higher and uploaded it in a separate STL file.</strong></p><p>As soon as I started my very first print with my new Prusa Mini I decided I needed a way to see the nozzle up close if I wanted to do the best 3D prints I can.&nbsp;</p><p>I designed this rotating clip-on mount that attaches to the side of a fan, accepts a 4.3mm wide otoscope (ear camera), and lets me watch my printer churn stuff out on my computer, phone, or raspberry pi.</p><figure class="image image_resized" style="width:64%;"><img src="https://media.prusaprinters.org/media/prints/68906/rich_content/dd0b8ac3-e949-4f50-9d6e-61d5cf8f5688/20210610_220104.jpg#%7B%22uuid%22%3A%22e2faeff3-d68a-40ec-b920-ec29a5a34346%22%2C%22w%22%3A1515%2C%22h%22%3A1780%7D"></figure><figure class="image image_resized" style="width:64.28%;"><img src="https://media.prusaprinters.org/media/prints/68906/rich_content/8fadd8aa-bfbe-4f3b-8b03-bf26e8c79580/my-snapshot_4.jpg#%7B%22uuid%22%3A%2258b9418b-4960-4028-a7a9-1683f09e5bea%22%2C%22w%22%3A1920%2C%22h%22%3A1080%7D"></figure><figure class="image"><img src="https://media.prusaprinters.org/media/prints/68906/rich_content/b5839f29-4573-4893-8d26-4f305e570534/fusion360_4kvq98akmm.png#%7B%22uuid%22%3A%22b05b44ab-aaa0-4ea5-9469-82a9fb408d51%22%2C%22w%22%3A1339%2C%22h%22%3A539%7D"></figure><p>The angled hole for the Otoscope is 3.35mm wide, with a shallow 5.55mm diameter opening so the camera can slide in a little for better focus.</p><p>In the one print I've done those dimensions were exactly 3.3mm and 5.5mm, but I had to shave a tiny bit of material away with a drill bit so I adjusted them slightly. Please let me know if you have a similar otoscope and it fits on the first try. The bolt hole fits an M4x8.</p><p>This is the first thing I've designed and put online like this. :)</p>
