Created a fan riser for my NZXT H9 flow case via Fusion. The orignal fan mounting in the case is recessed and does not allow viewing of the infiniti mirror fans. The print raises the fan 25mm and angles it 10° foward. The wires of the fan exit the back and are unseen. I thinned and hollowed it for optimal airflow, as well as limiting the use of material and allowing for a faster print time. 

Mount the fan to the adapter 1st, then install into the case and secure.

Enjoy!
