Feet for Fujitsu Futro S920 mini computer to make it more stable when stood upright.
The feet have small notches to prevent them from sliding front and back when moving the computer, but it's not a tight fit, so when lifted, they'll fall off. There are some holes on the bottom of the case to screw on original feet, so if you have those screws, this is probably not the best design for you.

The author marked this model as their own original creation.
