Just a keyring with the Gilera logo on it.

Width: 35.50mm
Height: 58.75mm
Thickness: about 4mm
Keyhole diameter = 3.0mm

You could ofcourse make the keychain smaller by adjusting the scale in your 3d software.

The print I did was in a rush, so it didn't turn out great. If you printed this thing, please don't hesitate to post a make!
