Arduino Nano Case for Sim Hub Wind Simulation

Small case to house an Arduino Nano V3 running a Simhub Windsimulation sketch. The protoboard breaks out ground and the 3 PWM signals to the 4-Pin fan connectors and connects an external 12V powersupply. I used these headers https://www.printables.com/model/78097-4-pin-fan-header 

Printed in PLA on Bambulab A1 with 0.2 Layer Height. It fits nicely and doesn't need glue in my print.
