Break out the board support from the middle of the network port cutout by twisting it. Align the semi-circular cutouts on its edges with the plastic pins under the ethernet port on the Raspberry Pi, and press in.
Twist the break-out piece.
Discard the middle piece.
Take the break-out board support
And place in positon under the ethernet port on the Raspberry Pi.
Choose 4 of the 7 possible positions on the Raspberry Pi board edges for the remaining board supports (see Figure 3). The ideal position of the board supports depends on the exact clearances of each case and board combination, so the position may need to be adjusted for best fit. While the case can be constructed without these, the Raspberry Pi may rattle in the case without them.
For the early model Raspberry Pi (without mounting holes) support the board edges at up to 4 places with the included board supports.
Place the Raspberry Pi onto the case base and clip on both side pieces, ensuring the cutouts match the ports and the etched writing faces outwards. Hold the Raspberry Pi and base in your left hand and the side in your right hand. Place the clip and farthest tab into their respective slots and slide the side towards you and inwards until it clips in.
Hold the side and click on the the base.
Repeat with the second side.
Add each end piece, one at time, by hooking both lower, fixed hooks on the side piece into the corresponding hole in the end. Then, while pressing the textured handle for the top clip (one with each thumb) press the end (with both index fingers) over the depressed top clips.
Repeat with the other end.
Add the top by operating both clips and placing it down into the open slots.
The constructed case.
The Clip-R-Pi is designed to stack, just take two and place one on top of the other. They can be stacked with both in the same orientation, to keep the ports alligned or rotated 180 degrees to offset the ports. Stacks shouldn't be more than 4 Raspberry Pis tall to reduce the risk of falling.
