HP DL380 G5 Drive Tray
HP Drive Tray/Caddy for DL380 G5 and similar models.
The latch is simple like the dummy trays.
I've added some basic supports for overhangs. However, this is a very challenging print and your printer must be able to handle long bridges very well.
I'm planning to add a model with a complex latch similar to the actual HP drive tray/caddy.
