Pixel 3a desk dock

thingiverse

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: 1. all buttons and complete screen accessible when docked 2. doesn't muffle the sound from the phone speakers 3. automatically plug-in when I set the phone in the dock 4. no lateral stresses on the charge port or charge cable 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 bottom-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. 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. 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.
