Linear actuator with stepper motor from cd/dvd optical drive

<p>[UPDATE]</p> <p>There is my upgraded model with integrated limit switches: <a href="https://www.thingiverse.com/thing:5173219">https://www.thingiverse.com/thing:5173219</a></p> <p>I needed a lot of tiny linear actuators so I designed something like this.In most cases all the parts required to build this can be found in computer optical drives, but I also added a version with linear bearings instead of brass bushes(not all drives have them).The linear bearing version is better in my opinion but both work well.Parts needed from cd/dvd drive:</p> <p>-3mm shaft</p> <p>-linear stepper motor</p> <p>-slide bushes (if there are no brass slide bushes in the drive, use 2 LM3UU bearings)</p> <p>-M3 screws</p> <p>You should use glue on parts placed on shaft (clutch and nut).In some stepper motors the holes must be enlarged to fit M3 screws</p> <p>How it works: <a href="https://youtu.be/nML0P0cFWjI">https://youtu.be/nML0P0cFWjI</a></p> <p>Linear bearnigs if needed(choose LM3UU option) : <a href="https://s.click.aliexpress.com/e/_AsEc8S">https://s.click.aliexpress.com/e/_AsEc8S</a></p> <p>Step files: <a href="https://drive.google.com/drive/folders/1dXIVqyzUB_mrgUrEh6H3EsR2uR3m4u6S?usp=sharing">https://drive.google.com/drive/folders/1dXIVqyzUB_mrgUrEh6H3EsR2uR3m4u6S?usp=sharing</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>0.1 for nut and clutch</p> </p> Category: Robotics
