Updated version 2: Fix the drive rail part STL. This is a 4-in-3 hard drive cage with cooling fan. It fits four 3.5″ drives in to three 5.25″ slots. It can be used inside a standard PC case or on its own with no case. I often need portable drive cages for moving drives around…
I made a 3D printed block-off plate so I can remove the DVD drive.
