getting into the final run-through of fan 1 before printing.
The hole diameters are 1.902" and 1.4". I dont know the plastic shell thickness.
But the fan grill will extend 0.17" above the shell and from the top of the grill to the bottom of the fan blade is 0.44"
OK with those dimensions??
ALSO note the insertion lip in the upper right to aid in centering the fan in the hole.
