Sometimes key handles/key covers break, this is a 3D model for my bike key, it broke a while ago and I just realized that I could do something with my 3D printer.

My key has a hole on it, so I just add a hole on the case to use an m3-.50 screw and nut to be sure that it won't fall down from the cover.

Print it to the rounded part up, this will be easier for you to remove the supports.

A M3-.50 nut is required.

If this helped you lemme know.

If you feel like donating something, buy me a coffee.
