Clamp screw and end stop for 1/2 inch schedule 40 PVC pipe. The end stop is adjustable to the length of pipe. I designed a hole in the set screw to glue in a 1/2 piece of a small brad to use as a spike to firmly grip the end stop onto the pipe. There is also a hole in the screw end to affix the screw to one end of the pipe with a small screw.
The STL is has all parts in a single file that can be split in the slicer is necessary.
