PSP Go Backplate v3

prusaprinters

<p>The PSP Go uses the same battery connector as the Vita 1000. I found a few extended backs, but they all required taping the battery in place. On top of that, there was no way to access the M2-to-SD adapter from the outside.</p><p>I used Hipcat's model as my base, and I redrew nearly every bit of geometry.</p><p>First, I sized the internals to snugly hold a standard Vita 1000 battery in place. There's a “PSP” cutout that can be left blank, or you can print the “logofill” file to make the logo the color of your choice. To help ensure a flat print, each letter has some 1-layer tabs designed to be easily cut away with a craft knife.</p><p>Next, I had to figure out how to fit an M2-to-SD adapter so it could be accessed from the outside. Fortunately, removing the OEM battery freed up a bunch of space near the top; it was just barely wide enough to support the adapter. But I needed to find a way for the adapter to stay in place when inserted <strong>after</strong> the battery.</p><p>A tiny puzzle-piece insert did the trick. Note that the bottom is <strong>not flat</strong>! In order to accommodate the battery, it's a little wider near the puzzle-piece end. I recommend printing vertically per the attached gcode.</p><p>After that, I made some more improvements: reinforced the screw holes; improved the fit of some of the doors; added a slot for the wi-fi antenna; bolstered the area near the lanyard hole; added small “wings” because it strengthened the design and was also more comfortable to hold.</p><p>During assembly, I used kapton tape to hold the battery, the antenna, and the SD adapter in place. I then put a scrap foam block on top of the SD adapter, to make a snug fit and prevent the adapter from shifting. Remember to place the SD adapter <strong>with the pins visible</strong> to make sure the SD is easy to put in and take out.</p><p>Uses the original four back screws.</p><p>I've used this model for two different builds, and with M2-to-SD adapters from two different makers. Both felt solid and held together nicely.</p><p>Be careful not to overtighten the screws near the shoulder buttons - it can make the shoulders stick down.</p>
