<p>Turn your Raspberry Pi 2 and Raspberry Pi 7" Touchscreen into a completely custom tablet.</p> <p><em>This design is still a work in progress. Cable lengths and required hardware have not been tested/determined.</em></p> <p><em>Work is still on going to find a fitting battery to go inside.</em></p> <p><strong>Features</strong></p> <ul> <li>Ability to mount the Screen to the shell without the use of glue on your screen.</li> <li>Off center mounting location for Raspberry Pi for a larger empty area.</li> <li>USB &amp; Ethernet external access</li> <li>GPIO external access (optional plug)</li> <li><p>Pi Camera mount on back (optional dummy plug) This design is derived from <a href="https://github.com/MCMElectronics/Raspberry-Pi-Tablet">MCM Electronic's Raspberry Pi Tablet shell</a>.</p> <h3>Print Settings</h3> </li> </ul> <p><strong>Rafts:</strong></p> <p>Doesn't Matter</p> <p><strong>Supports:</strong></p> <p>Yes</p> <p><strong>Resolution:</strong></p> <p>0.1mm</p> <p><strong>Notes:</strong></p> <p>If you cannot print at 0.1mm resolution, it should still work. You will have to sand and trim the pieces though.</p> <p>Print List:</p> <ul> <li>Shell</li> <li>Pi Plate</li> <li>Back Plate</li> <li><p>GPIO Plug +<em>Optional</em> if you don't use the GPIO</p> </li> <li><p>Camera Insert<em>or</em> Camera Dummy Plug</p> <ul> <li>Print the dummy plug only if you are not using the Raspberry Pi Camera</li> </ul> </li> <li><p>Mount Frame</p> <h3>Post-Printing</h3> </li> </ul> <p><strong>Finishing</strong></p> <p>Test fit all pieces together.
