<p>// Here you can find my new project which also use parts from optical drive <a href="https://www.thingiverse.com/thing:5201443">https://www.thingiverse.com/thing:5201443</a></p> <p>This is upgrade of my previous version I posted here.I also added second actuator without external shaft.These models differs from the previous version in that they allow to install limit switches inside actuator frame.</p> <p>Parts needed from cd/dvd drive:</p> <p>-3mm shaft</p> <p>-linear stepper motor</p> <p>-slide bushes</p> <p>-M3 screws</p> <p>Optional mouse limit switches - im using these, model D2F-L3 <a href="https://s.click.aliexpress.com/e/_9wbixc">https://s.click.aliexpress.com/e/_9wbixc</a></p> <p>How it works &amp; lift test: <a href="https://youtu.be/_XdJ7rqTPUw">https://youtu.be/_XdJ7rqTPUw</a></p> <p>Step files: <a href="https://drive.google.com/drive/folders/1Xz385k_Gf5eYcKJpisetwqBsru13ryDk?usp=sharing">https://drive.google.com/drive/folders/1Xz385k_Gf5eYcKJpisetwqBsru13ryDk?usp=sharing</a></p> <p>// update</p> <p>added 2 files - A_Frame_with_bearing &amp; A_Cover_with_bearing - this is model A but with fixed mount for LM3UU bearings if you dont have slide bushes.I printed it and all fits well but didnt tested on working actuator</p> <p>Link to bearings for this frame (LM3UU) <a href="https://s.click.aliexpress.com/e/_AsEc8S">https://s.click.aliexpress.com/e/_AsEc8S</a></p> <h3>Print Settings</h3> <p><strong>Rafts:</strong></p> <p>No</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div> <p><strong>Resolution:</strong></p> <p>0.2 for frame &amp; cover, 0.1 for nut</p> </p> Category: Robotics
