Electric aerial internal gear

Guys, this might be a long shot, but does anyone know where I could get hold of this cog?

Basically my electric aerial does not work, the motor works, I can hear it working. Today I decided to investigate and took it out and took it apart. The culprit looks like it’s this cog that has been worn down by the metal worm gear on the motor.

Please see the photo attached. Any guidance will be highly appreciated.

There’s a guy here who can 3D print plastic parts like that. I wish I could remember which topic it was under but read through them and when you find it, ask him if he can print you one. I think it was a topic about glove box.

Thanks wolf, yea I did think about 3d printing it, I’m just uncertain how strong it’s going to be, or how long it will last. I don’t understand why it’s even made from plastic. Silly design, if it was brass, it would have been great.
