HDD Rack
thingiverse
Two of these units side by side will fit perfectly in a rackmount case. This makes it easy to have 20 HDD inside even a short 4U case. I'm still working on a tool-less way to secure the drives if anyone has ideas. Also still working on ways to secure the two units together and to the case itself. High level of infill (80+ recommended) to help increase the strength of the thin walls. This doesn't use up too much more fillament. Rotate and Print it with the stops on the print bed and it will not require any supports.
