This revision contains all the parts files in the original posting, but I have added the OpenRail Gantry Plates in all 4 sizes (20mm, 40mm, 60mm, 80mm) as well as some assemblies (V-Slot Wheels, Brackets with bolts and tee-nuts, etc.). These will be found in the assemblies folder of the zip file.
As before - there is also a folder for your Design Library containing Solidworks Feature Library parts files (.sldfp) of the OpenBuilds V-Slot extrusions for your use as well.
