Alienware Area 51 Case Front Fan Adapter Bracket 120mm
Alienware Area 51 case fan adapter.
EDIT
v6 now available - Added reinforcements and it now looks much more like the original bracket
When printing use auto supports that only connect to the bed - printed mine at .16 layer height
Just be careful of the small plastic brackets that connect to the case as they can snap easily.
I plan to redesign this to hold either 3 fans or try and get it to hold 2 - 120mm fans
