3D Systems Cube 3rd Gen Parts

[NON...@kirkwoodpubliclibrary.org]

Does anyone have any used Cube 3rd Gen printers from 3D System or parts? I am looking to replace the step motor on mine and the square shaft has worn down to a circle and will not engage with the cartridge feed gear anymore.

I have been in touch with 3D Systems, but they have been less than helpful.

Any help or point in the right direction would be appreciated.

Thanks!
