This is a replacement tray for the Icy Dock ToughArmor MB839SP-B which is a PCIe card for your pc that adds a hot swap-able 2.5 inch drive bay. You can often find these cheap on ebay missing their tray and I purchased several. This replacement tray allows you to use the device normally but adds a small compartment for a USB thumb drive, or in my case a yubi key as well as some rolled up cash. Between it and the drive it contains everything I need to regain access to all my accounts and access all my data in the case of a house fire or the the like since I live in wildfire territory in oregon.
The sliding cover is tight enough so as to not fall off in transit. I printed mine in PETG at .4mm layer height in about an hour.
Included are stl files for the tray and the cover as well as the blend file.
