Ratrig Toolhead upgrade for V-core 3.1 just went out of beta. My previous design for beta 2 had a modified toolhead front piece that accepted removable probes plus modified klicky arm to fit it. Ratrig has now modified the front piece to accept removable probe mounts as well, so I just redesigned the klicky probe arm to fit on the original ratrig part.
The author marked this model as their own original creation.
