I didn't like hacking up a servo mount (plus I didn't have one that would fit quite right) and then screwing it into the gear so I made this quick little hack using one of the pully mounts from the servo bed project and shaping it up and slapping the gear on top. This should fit on a standard servo and a screw can drive through the center into the servo cap. It might be a LITTLE tall so you can shave some of the bottom off. I'll probably make a cleaner version later.Should be able to just print and use.
