Interstellar Snail Model A Backplane Hard Drive Rack supports 3.5 and 2.5-inch hard drives

I found a simple hard drive rack on MW, but it couldn't utilize my Interstellar Snail Model A backplane to connect the hard drives. So I made one myself, adjusting the length of the center hole to accommodate both 3.5 and 2.5 inch hard drives simultaneously without needing extra brackets for the 2.5-inch drives.

To save material and improve ventilation, I used a modifier to add a honeycomb pattern. If you don't like it, simply remove the modifier.

Aside from the backplane, you can also choose not to use it and connect the power and SATA cables directly to the hard drives.

You will need M3.5 screws to secure 3.5-inch hard drives.

You will need M3 screws to secure 2.5-inch hard drives.

There is no shock absorption, you can buy self-adhesive EVA foam and stick it to the bottom for vibration damping.
