Cell Phone Mount for 2014 RAM 1500

prusaprinters

<p>This is the base for a cell mount for a 2014 RAM 1500. It installs without permanent modification of the truck, in a weird mystery slot in the center console. It's very close to a 12V socket in the console, to connect a charger.</p> <p>I have no idea whether it would fit in other models or years. But if anyone tries it, let me know and I'll add a note here.</p> <p>This thing is just a generic base and arm. A phone-specific cradle attaches to it. I designed one for my <a href="https://www.prusaprinters.org/prints/45266-samsung-galaxy-s10-car-mount">Samsung Galaxy S10</a>.</p> <p>Or you can design your own phone-specific cradle. Requires a 20mm ball-socket (I made mine 20.15mm for tolerance), and a 1"-12 UNF thread.</p> <p>I've included a sample ball-socket that you can build onto. You don't need that part if you're pairing this with a phone cradle that has it built-in, like my <a href="https://www.prusaprinters.org/prints/45266-samsung-galaxy-s10-car-mount">Samsung Galaxy S10 cradle</a>.</p> <h3>Print instructions</h3><p>I print the threaded parts (clamp nut and socket) at 0.1mm layer height.</p> <p>The base, arm, and ball all have very small contact area for their height, and so should be printed with a brim for better adhesion.</p> <p>Print the ball, clamp-nut and arm with "Seam position" set to "Random", to avoid seams on the ball-joint mating surfaces.</p> <p>The socket part (if you want it) is printed with supports everywhere (not just on the build-plate), to help with the shape of the threads. It's not too difficult to clean the support material out of the external threads.</p> <p>Base is printed with 15% gyroid infill. The arm, ball, and clamp nut are printed with 25% gyroid for greater strength.</p> <h3>Smoothing</h3> <p>I did a mild acetone-vapour smoothing on the arm before assembly, to help with the layer adhesion. Otherwise, the arm is liable to break.</p> <p>Optionally wet-sand the ball a bit. I didn't find it necessary. The rough surface of the ball and socket actually helps to lock the joint in place without too much force on the clamp nut.</p> <h3>Assembly</h3> <p>Assembled with ABS glue.</p> <ul> <li>Before assembly, dry-fit it and fiddle with the position in your truck, until you're comfortable with it. Use masking tape and a pencil to mark the desired angle for the arm.</li> <li>Glue the arm into the socket on the base.</li> <li>Slide the clamp nut over the arm (it's impossible to put on later).</li> <li>Glue the ball onto the arm.</li> </ul>
