This is a stackable case for the Orange Pi PC in a cluster configuration. The Orange Pi fits inside and the cases can be stacked on top of each other in a cluster configuration.
Two versions are available, one for and one without a bracket for a standard Pi fan (30mm X 30mm).
There are also two types per version, one that fits the Orange Pi and one for the top of the stack only.
Suggested configuration is a maximum of 4 Orange Pi PC's on top of each other. Including the top, a total of 5 prints are required for this configuration.
Update 28/05/16: Made the holes for the fan bolts slightly bigger.
Update 05/06/16: Received some new fans which had longer bolts so made the supports of the fan version 5mm higher for more clearance. Added "longer" to the filename.
