So Good i printed it twice, first time in the sample filament supplied with my cr-10 with the model rotated so it was upright with the fangs up. 20% infill i believe at .2 layer height. the turbine mount broke on that print so i held one side down with a rubber band while it printed again on the filament that arrived the next day
second time around was on 3dFillies PLA+ in the normal orientation of that file. printed on a raft, with supports that only touch the bed and i increased wall and ceiling thicknesses by 50% with a 50% infill...which was rarely used due to increased wall thickness. that one broke at the "hook" for the mounting plate. so i'd suggest finding an orientation that doesn't leave thin pieces printed square on to the tension
It is completely possible to mount this fang with no additional screws. just use two on the cooling fan.
