<p>Cradle for mounting a Samsung Galaxy S10 in a car.</p> <p>Features:</p> <ul> <li>Simple drop-in</li> <li>Built-in wireless charger</li> <li>Holds uncased phone in landscape orientation</li> <li>Lockable ball-and-socket joint</li> <li>Clearance cutout for phone's cameras</li> <li>Side buttons and USB-C all accessible</li> </ul> <p>Wireless charging capability is provided by an integrated <a href="http://www.gikfun.com/belong-to-you-modules-c-68/qi-wireless-charger-pcba-circuit-board-coil-micro-usb-port-diy-p-734.html">Gikfun Qi Wireless Charger EK1854C</a> (available <a href="https://www.amazon.ca/dp/B073W7P5T8">from Amazon</a>).</p> <p>This cradle attaches to a vehicle-specific mounting base. I have designed bases for two vehicles:</p> <ul> <li><a href="https://www.prusaprinters.org/prints/45232-cell-phone-mount-for-2006-infiniti-g35">2006 Infiniti G35</a></li> <li><a href="https://www.prusaprinters.org/prints/45242-cell-phone-mount-for-2014-ram-1500">2014 RAM 1500</a></li> </ul> <h3>Print instructions</h3><p>The side and bottom hooks should be printed on their sides, to get their strong axis oriented the way we need.</p> <p>Print four side hooks, and two bottom hooks.</p> <p>The threaded socket should be printed with 0.1mm resolution, and full supports, to get clean threads. The support material is not difficult to remove from the external threads.</p> <p>The back plate is printed with 15% gyroid infill. The socket is 25% gyroid, for strength.</p> <p>Print the thin front cover plate face-down, to get the best surface texture.</p> <h3>Assembly</h3> <p>The cradle will be assembled with ABS glue. It's something of a fiddly process.</p> <ol> <li>Trim off any brims</li> <li>Clean support material out the threads of the socket</li> <li>Wet-sand the edges of the side and bottom hooks<ul> <li>Make sure they fit in the recesses made for them</li> </ul> </li> <li>Wet-sand the mating surfaces of the back and front plates<ul> <li>They will be glued together later, so we want to minimize bumps and ridges</li> <li>Don't get confused about which side of the front plate is which</li> </ul> </li> <li>Dry-fit the side and bottom hooks<ul> <li>Dry-fit the hooks in their recesses, in such a way to give a loose fit for the phone.</li> <li>Dry-fit the front plate</li> <li>Position the phone, centered on the cradle.</li> <li>Adjust the positions of the hooks so that the phone can slide in and out easily, </li> <li>Without moving the hooks, remove the phone and front plate.</li> <li>Without moving the hooks, use a sharp knife to score a line across each hook, and onto the surrounding back plate. This marks the desired position for gluing.</li> </ul> </li> <li>Install the hooks. Working one-at-a-time:<ul> <li>Remove the hook from its recess</li> <li>Apply a small amount of ABS glue in the recess</li> <li>Install the hooks, aligning the score marks</li> <li>If any glue squeezes out to the top, wipe it level</li> <li>Keeping pressure on the hook, wait a couple minutes for the glue to set.</li> </ul> </li> <li>If necessary, re-sand the top mating top surface around the hooks, to remove any roughness from glue seepage.</li> <li>Mask off the area on the back plate where the front-plate's camera cutout is (I wish I had done this... learn from my error.) Leave a tail hanging out the edge so the tape can be removed quickly.</li> <li>Install the charging coil and circuit-board.</li> <li>Working quickly now, install the front plate.<ul> <li>Apply ABS glue to the entire mating surface of the back plate.</li> <li>Peel off the masking tape from the camera cutout area.</li> <li>Bend the front plate and install it under the hooks.</li> <li>Press the front plate and back plate together, working around everywhere.</li> <li>Keep pressing for a few minutes while the glue sets up.</li> </ul> </li> <li>Install the socket<ul> <li>Apply ABS glue to the inside edge of the socket hole, and a small distance around the hole</li> <li>Apply ABS glue around the mating parts of the socket</li> <li>Install the socket, and hold it in place a few minutes while the glue sets</li> </ul> </li> <li>Allow 24 hours for the ABS glue to fully cure</li> </ol> <p>When the ball-and-socket is first put together and the clamp nut tightened, the threads may be very tight. Work the clamp nut on and off a little bit at a time, and the threads will loosen up.</p>
