This is a mounting Tray to fit an SSD into a dell optiplex 9020 (also fits some other models).
It is a single piece solution to replace the blue dell caddy and 3.5" to 2.5" adapter. I have been using these sucessfully now for over a year. I will upload some photos soon.
I print at 0.2mm layer height, 30% infill using PC-ABS filament and they print fine without any support or raft.
After printing you will need to remove the two round bits on the corners (used to aid bed adhesion). Screw the two halfs to the ssd and insert it into the pc. I usually use self tappign screws to hold the bracket into the computer case as the screw holes in newer Optiplex 9020's are not tapped. I have also used these in Vostro 270 / 460 but these models do have tapped screw holes so you can use normal computer screws instead of self tapping screws.
