A stackable holder for 3.5" external hard drives, designed to keep multiple drives organized without taking up a lot of desk or shelf space. If you’re running several external HDDs, this makes it easy to build a clean, vertical stack that stays stable and easy to access.

The holders are designed to stack securely on top of each other, so you can add more as your storage grows. The shape helps keep everything aligned and prevents the stack from shifting during normal use. 

Features

• Safety lip in the front – keeps drives from sliding out on their own
• Easy access – drives can be removed without taking the stack apart
• Cable access from the back – plug in and unplug drives while stacked
• Warp-friendly geometry – adjusted to print more reliably
