Chainable storage boxes for Mobiles/Hard Drives

My desk was cluttered with hard drives, the Blu-ray burner, their cables and other smartphones. So I designed these elegant boxes to put things in order.
The boxes are of two types: for 4 hard drive or smartphone slots, for a Burner or CD/DVD/Blu-Ray slot with their cases.
Both types of boxes can be chained as desired, depending on the needs of the moment.
The bottom is perforated, and has reserves for gluing 10 mm diameter pads.
I printed these boxes with rPLA Corn filament, which gives them a very nice decorative wood-like appearance.

Printing without supports.
