It might not look terribly impressive at first glance, but think for a second on how functional – and cheap – this simple laptop design is. It is highly portable, requires nothing you do not already own and costs next to nothing to construct.
The essential steps are almost self-explanatory: collect a pair of scissors, a used cardboard box and print out the simple shapes you will need to overly on the cardboard in order to begin cutting out the three pieces to create the stand.
The pieces require now glue or fasteners, which means they can come apart as easily as they go together for maximum portability and future reuse. The instructions for the above-shown version can be found in greater detail at Green Upgrader and a slightly more complex (but cooler-looking) Steampunk version can be seen at Thingiverse.
