Sipeed Nano Cluster Case

This is a case for the nano cluster that I printed. I wasn't happy with the cooling stock and the limits seemed to be hard set in the image provided by Sipeed. Rather than recompile linux I opted for an easier low tech solution. The case takes 4 M3 threaded inserts at the bottom to hold the Noctua 5V PWM NF-A6x25 fan. I then used a 3d printing pen to connect the nano cluster rivet style to the offset pegs to hold it in place. The stock screws could be used, but I damaged one in the past so didn't want to reuse. A simple USB to 3pin/4pin PWM 5V USB Sleeve Fan Power Adapter Cable with USB Fan Governor Speed Control Knob ON/Off was used to power and control the fan. Now instead of being at 87C at idle on node one I'm sitting at 50C at about 50% fan speed.
