Phanteks T30 + Exhaust fan duct clip

Wanted to attach the following fan duct to my FormD T1 2.1 case with Phanteks T30 exhaust fans and didn't want to use screws. I did slice the top of the fan duct to be 8mm tall so it sits against my top panel.

This clip snaps on easily and snug. It might fit other fans as well, but haven't tested it as I only have these. As long as the fan duct is 4mm, this will fit without modification. 

I printed it in ABS. Depending on your temps, PLA might soften.
