Shortened spring mount for the Tefifon

prusaprinters

<p>If you replace the pickup cartridge on a Tefifon (like <a href="https://www.prusaprinters.org/prints/68261-tefifon-replacement-cartridge-adapter">here</a>) you might find that the tracking force is too high. The adjustment range of the original mount for the spring/dampener-combination is limited:</p><figure class="image image_resized" style="width:40.18%;"><img src="https://media.prusaprinters.org/media/prints/68285/rich_content/555bc668-c726-4a31-8b6e-0182edff2508/spring_original.jpg#%7B%22uuid%22%3A%227626814d-280a-4fb6-bd99-150f728f428e%22%2C%22w%22%3A836%2C%22h%22%3A1124%7D"></figure><p>So I designed a 3d printed replacement part to allow lower tension of the spring:</p><figure class="image image_resized" style="width:56.57%;"><img src="https://media.prusaprinters.org/media/prints/68285/rich_content/0a183324-f098-41db-bc3c-6ca41f4e42a1/spring_mount.jpg#%7B%22uuid%22%3A%22bc8e45ce-d723-484e-af60-5c8d32976e37%22%2C%22w%22%3A879%2C%22h%22%3A652%7D"></figure><p>First tests on the device were promising:</p><figure class="image image_resized" style="width:33.85%;"><img src="https://media.prusaprinters.org/media/prints/68285/rich_content/8db6b4a5-ad52-4aa9-821f-83ffa34ebff2/spring_mounted.jpg#%7B%22uuid%22%3A%22b93f9fac-5d35-4576-ab50-2c07088c86cc%22%2C%22w%22%3A988%2C%22h%22%3A1331%7D"></figure><h3><strong>Printing</strong></h3><p>Because it is a very thin part, I have printed the holder using Prusa's PC-blend filament in 0.3mm layer height. But I guess it might also work in PETG.</p><h3><strong>Design and Source Code</strong></h3><p>The mount has been designed using OpenSCAD. I have provided the source code for download, so you can adjust the design to your needs.</p><h3><strong>Happy printing!</strong></h3><p>If you like this design, then <strong>please leave a like</strong> and also <strong>post a photo in the comments</strong>.</p><p>Looking for more Tefifon related stuff?
