Western Digital External Drive Shelf

This is a shelf to stack Western Digital My Passport USB 3.0 Hard Drives on a Desk.

It provides ventilation on the sides and middle rack, as well as a lip on the back of the unit to protect fit the drives onto the shelves.

I have only printed the second iteration of this design (ShelfMk2.stl), and can't really vouch for the original. I have included the Blender files and STL for the original in case anyone wanted them.
