I have remixed the two parts in the original to be one part that fits the Orballo version of the P3Steel frame.
The lead screw hole will need to be worked with an 8/9mm drill bit as I have not adjusted the original measurements.
The Lead screw holes will need to be worked with a 10mm drill bit as I found that the screw was fouling on the original hole.
You will also need to file where the frame slides in as I have given zero tolerance, not doing so will crack the part!
The original design worked great, however I felt that I needed a more fixed alignment
