Hi, Do you know the link to find the Prusa i3 Z axis mounts

Hi, Do you know the link to find the Prusa i3 Z axis mounts ( Top & bottom ) The ones that move the Z axis out wider from the frame. The normal mounts are inline with the frame. The one’s I am looking for push the z Axis outside the frame line. Hope everyone understands what I am looking for. I looked on Thngiverse but can not find them.
Thanks
