Pixel 3a desk dock with audio

<p>I wanted a custom-made phone dock that keeps my phone in reach and keeps it charged when I'm at my desk. The dock fits a Google Pixel 3a with a Spigen Rugged Armor case, which has dimensions of 74.2 mm x 11.2 mm in the cradle. I had the following requirements:</p> <ol> <li>all buttons and complete screen accessible when docked</li> <li>doesn't muffle the sound from the phone speakers</li> <li>automatically plug-in when I set the phone in the dock</li> <li><p>no lateral stresses on the charge port or charge cable</p> <p>Item 1 was met simply by shaping the case correctly. Item 2 required the design of tunnels with smart deflection angles to redirect sound from the down-firing phone speakers to front-facing openings. This worked out really well, actually increasing the volume of sound that you here compared to the phone simply sitting on the desk.</p> <p>Item 3 required me to design a cord gripper with barbs that holds the stock charge cable firmly and doesn't move at all within the cradle. I designed the cable gripper as a symmetrical half, so that you print two copies and invert them on each other to grip the cable. This assembly is then inserted into a tight chamber in the base, guaranteeing a tight hold and no movement during phone insertion/removal. Tight tolerances on everything guarantee that the phone always seats perfectly to meet item 4.</p> <p>One hand insertion is fantastic. The next version may include an eject button to push the phone up from the cable connection for easier one-hand removal.</p> </li> </ol> <h3>Print instructions</h3><p><strong>Printer Brand:</strong> Prusa<br/> <strong>Printer:</strong> I3 MK3S<br/> <strong>Rafts:</strong> No<br/> <strong>Supports:</strong> Yes<br/> <strong>Resolution:</strong> 0.2 mm<br/> <strong>Infill:</strong> 15%<br/> <strong>Filament:</strong> Prusament PETG Black and Orange<br/> <strong>Notes:</strong></p> <p>I printed two copies of the orange cable gripper first. No supports needed for that. Then I printed the two base pieces in black. The taller base piece requires some minimal supports to the bottom but nowhere else. My next version will modify the snap-together design to make it printable without supports.</p>
