<h3>Changelog:</h3><ul><li>June 24, 2021:<ul><li>After working with the mounting rack in practice for a while, I have significantly optimized the dimensions.</li><li>In particular, it is now much taller, so that there is also enough space for the motor underneath. Now the mounting rack is suitable for all reasonable orientations of the Tefifon known to me.</li><li>Also the parts have been modified to bend less and the distances to the Tefifon have been minimized. So the Tefifon sits in the rack much more stable.</li><li>Please note that the screw locations on the plate have changed!</li></ul></li><li>June 7, 2021:<ul><li>Fixed some dimensions and improved the look</li></ul></li><li>June 6, 2021:<ul><li>Improved the design by adding an additional step for holding the top of the device when it is not held by screws</li><li>rounded some edges</li></ul></li></ul><h3>Description</h3><p>When restoring old Tefifon units I found it very difficult to work on the chassis without damaging delicate parts. So I designed this simply mounting rack.</p><p>Simply print the 4 corners (PETG, 0.3mm layer height), get a 301mm&nbsp;x 193mm plate and mount the corners with 12 pcs 3mm … 3,5mm countersunk screws. The outermost screws must be mounted at a distance of 250mm / 140mm to exactly match the size of the device:</p><figure class="image"><img src="https://media.prusaprinters.org/media/prints/68207/rich_content/ca3a5dd2-168a-4aaf-a04f-d160e4e62592/1.jpg#%7B%22uuid%22%3A%2263ef7682-e33f-4852-b672-d09164926319%22%2C%22w%22%3A943%2C%22h%22%3A791%7D"></figure><p>Now you can put the rack on to of the Tefifon and flip it upside-down:</p><figure class="image"><img src="https://media.prusaprinters.org/media/prints/68207/rich_content/71444589-eb19-49db-a3da-a90c75b5f905/2.jpg#%7B%22uuid%22%3A%22620cf0a4-c658-4bfc-8eef-0986a570c085%22%2C%22w%22%3A943%2C%22h%22%3A791%7D"></figure><p>So you can work on the underside of the device without any worries:</p><figure class="image"><img src="https://media.prusaprinters.org/media/prints/68207/rich_content/754c4dfe-f7d1-490b-a12c-4583beb4a02a/stand3.jpg#%7B%22uuid%22%3A%22c72c43f0-eb80-4bd4-b43b-568a836a2d10%22%2C%22w%22%3A1674%2C%22h%22%3A1204%7D"></figure><p>In the most current version of the design it also can be used to just hold the top part of the Tefifon (the chassis):</p><figure class="image"><img src="https://media.prusaprinters.org/media/prints/68207/rich_content/147e8148-c021-41f5-a69c-9a06a34bc78f/3.jpg#%7B%22uuid%22%3A%227c57fee3-a852-41f4-ba8f-e14e30b20474%22%2C%22w%22%3A935%2C%22h%22%3A724%7D"></figure><p>And you then can even flip this part and there is enough space for the motor underneath:</p><figure class="image"><img src="https://media.prusaprinters.org/media/prints/68207/rich_content/79273377-afac-4e18-b698-ded7570769bb/4.jpg#%7B%22uuid%22%3A%22d67c8386-b3f2-427f-bf51-0abbc59be5d8%22%2C%22w%22%3A1111%2C%22h%22%3A756%7D"></figure><h3>The finishing touch</h3><p>Since the rack is now frequently in use, I have embellished and waxed the plate. I also bolted <a href="https://www.prusaprinters.org/prints/68213-rubber-tpu-feet-for-the-tefifon-or-other-uses">rubber feet in original Tefifon design </a>to the bottom:</p><figure class="image image_resized" style="width:60.56%;"><img src="https://media.prusaprinters.org/media/prints/68207/rich_content/1935652b-34af-4187-b882-3485ca961ead/underside.jpg#%7B%22uuid%22%3A%225a12c016-b596-4a06-8611-2775fa1bcf14%22%2C%22w%22%3A883%2C%22h%22%3A681%7D"></figure><h3><strong>Design and Source Code</strong></h3><p>The corners have 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?
