40mm Snap On Pip Boy Fan Cover

thingiverse

I wanted the Pip Boy cover but as a snap on version. I gutted one of the Fibonacci cover, cut out around Pip Boy to the approximate size, Scaled up a bit to fit to the edge, then added a ring to the inside of the Fibonacci for more structure. It works nicely and there's enough room for the fan to spin without drag or worry about tapping the grill and it stopping the fan.
