Spacer for 120mm PC case fan. Originally made for Deepcool CH160 fan mounting bracket. Only one fan can be fitted and the fan sits too close to the tower cooler without this. This enables second fan to be added without colliding with the ATX PSU in this case.
Adjust the Z axis scale to suit your spacer thickness.
I recommend having both on top as intake, they sounds more quieter and cools better as well.
