Assembly Instructions

• Single Raspberry Pi
  1. Attach Pi to Base Plate
     1. Insert the 4 M2.5 x 5 mm pan head screws into the Raspberry Pi Mounting Holes
     2. Loosely attach the M2.5 x 4.5 stand offs to each screw on the pi
        • DO NOT TIGHTEN THEM YET
     3. Insert the M2.5 x 4.5 stand offs (male end) into the inner set of holes in the
  2. Base Plate
     1. Using 4 M2.5 hex nuts, put a nut on each stand off and fully tighten them
     2. Fully tighten the M2.5 pan head screws used to mount the pi
  3. Build Top Plate
     1. Using 4 M2.5 x 16 mm pan head screws and 4 M2.5 hex nuts, attach the 30x30x7mm fan to the plate with the fan blowing down
        • Depending on the length of wire on the fan, you can rotate the fan 90 degrees to take slack out of the wire
  4.  Build Stack
     1. Using the M3 x 24.5 stand offs, put a stand off's male end into the outer set of holes in the Base Plate (each corner)
     2. Use a M3 Cap Nut to Loosely secure each stand off
     3. Use the M3 pan head screws to attach the top plate, with the fan closest to the pi, to the 4 M3 x 24.5 mm stand offs
• Multiple Raspberry Pi's
  1.  Follow Single Raspberry Pi's Instructions
     1. Between Steps 3 and 4, do the following for each node
        1. Build Mid-Plate
           1. Attach Fan
              1. Using 4 M2.5 x 16 mm pan head screws and 4 M2.5 hex nuts, attach the 30x30x7mm fan to the plate with the fan blowing down
                 1. Depending on the length of wire on the fan, you can rotate the fan 90 degrees to take slack out of the wire
           2. Attach Pi
              1. Insert the 4 M2.5 x 5 mm pan head screws into the Raspberry Pi Mounting Holes
              2. Loosely attach the M2.5 x 4.5 stand offs to each screw on the pi
                 • DO NOT TIGHTEN THEM YET
              3. Insert the M2.5 x 4.5 stand offs (male end) into the inner set of holes in the Base Plate
              4. Using 4 M2.5 hex nuts, put a nut on each stand off and fully tighten them
              5. Fully tighten the M2.5 pan head screws used to mount the pi
           3. Build Stack
              1. Loosely attach M3 x 24.5 mm hex stand offs to each corner
        2. Attach Mid-Plate/s
           1. If you have more than 1 Mid-Plate, attach them to each other
              • Ensure they are all orientated the same way
           2. Tighten each node's M3 x 24.5 mm hex stand offs as you build them
