This instructable will show you how to quickly add Sugru Pi corners. Sugru molds like play-doh, then hardens into rubber. It sticks to most surfaces as it dries. We want to identify our placements to avoid closing off ports and add enough clearance so that the SD card can easily be ejected and solder pins clear the surface. This is a great solution if you need to mount your Pi to a conductive surface such as metal or … water?
Step 1: Identify your corners
Raspberry Pi model B and model B+ shown. Its important to identify the placement of the Sugru since we do not want to block off any ports. The object is to create rubber stand-offs to aid in board mounting on any surface. We will start with the Model B.
Step 2: Create Sugru balls
Looks like candy, but probably should not be eaten. Create 4 balls like you used to in elementary school by evenly dividing up the Sugru and rolling it between your two hands.
Step 3: Mold and place the balls
Place the Sugru on the 4 corners of the Model B board. Pay attention to avoid the Ethernet port, the power connector port, the pins and the SD card. Make sure you watch the mounting hole near the USB ports to allow for screw placement.
Step 4: Press balls and check for clearance
Press the board down firmly on a flat surface to shape the corners and make them nice and even. Check your clearance to allow the SD card to eject freely.
Step 5: Raspberry Pi B+
Repeat ball making and placing steps for the B+. The placement is a bit different due to board layout change. I decided to avoid the screw-holes. The only one really to worry about here is between the power connector and the HDMI ports. Just make sure you shape them to allow for connections.
