A replacement hard drive cover/caddy for a Dell Latitude E6520.
AFAIK it will also work on a E6320 and E6420.

I printed mine at .2 layer height with "supports from build plate only".
The holes are undersized to leave as much material at the end of the tabs as possible.
I use a small round file to open it up to final dimensions.

Works great and looks like OEM using black filament.
