Instructions
This works best when printed at a slight angle (say, 10˚) to the raft, like you see in the .stl version. The .blend version uploaded here is parallel to the raft, which leads to threads getting loose and breaking off if printed verbatim.
After you print this, it works best if you sand the tip into a slightly rounder shape. Apply spray paint if you like - might make the surface smoother, and give it a better look as well.
