Stackable Rack for External HDDs

This is a stackable rack for external HDDs. 

The body can be printed multiple times, stacked on of each other with a dowel joint and covered with the cap.

The ribs under the HDDs raise them and the holes on top, bottom and sides provide proper ventilation.

I printed the model with PETG, .2mm layer height and 15% infill.

Note: The pins fitting the top holes are optional, I used them for levelling my UPS.
