SDD Hot Swap tray
This is a tray to convert a 2.5" (SDD) disk to 3.5" size, specifically for use in a SATA Hot Swap bay.
What sets it apart from the other trays that can be found on Thingiverse, is that it is specifically designed to have the connectors at the exact same spot as a 3.5" disk to be compatible with hot swap.
Unfortunately this means the 2.5" disk can only be screwed to the tray on one side. On the other side one could use Duct tape to keep it in place.
To spare filament it hasn't the same height as 3.5", but since the scad file is included this could be easily adjusted.
