ZimaBlade: Double 2.5" HDD Stand

Simple stand for ZimaBlade which allows the board to be placed on the flat surface with storage hanging above the computer. I've designed it this way because I suck at cable management and I've mounted power/Ethernet/miniDP cables too short, leaving no way to raise the board up. It was easier to design the case this way than to redo the whole cablework \_(ツ)_/

Needs to be printed with supports on build plate.
