140-165mm wide phone arm

<p>This is a redraw of the arms of Arron Mollet's Mechanical Quick Grab/Release Phone Stand.</p><p>It should work with most remixes of that phone stand, including <a href="https://www.prusaprinters.org/prints/75318-all-metal-screw-triple-remix">my own</a>.</p><p>This arm is designed to accommodate phones 140mm to 165mm wide and up to 11mm thick. This is the specific range I needed for my STEM activity participants.</p><h3>Additional parts needed</h3><p>I used the rack with larger hook from this remix by Stephen Brooks: <a href="https://www.thingiverse.com/thing:3719672">https://www.thingiverse.com/thing:3719672</a></p><h3>Printing</h3><p>Load the <i>smaller-arms.3mf</i> into your PrusaSlic3r.</p><p>Alternatively load the STL twice into your slicer, and mirror one across either horizontal axis. I didn't include a left and a right version since they are mirror images.</p><h3>Remixing</h3><p>I had to redraw the arm because the original thing only included STLs. I have included the FreeCAD file, so you can have an easier time remixing.</p><p>I suggest you delete the fillets, change the sketch to resize the arm hook, and then finish the part as you like it, chamfer, fillet, whatever suits your fancy.</p><h3>Known issues</h3><p>Depending on your phone, the charger socket may be covered by the hook. The closer your phone width is to 140mm, the more likely this is.</p>
