16mm Ball Nut Arbor
cults3d
To keep the ball bearings from falling out of the ball nut when removed, you need to insert an arbor. It is possible for an arbor to fall out if your not careful so I added a short section of threads at the bottom that screw into the ball nut to hold it in place. The smooth section is 85mm long to accommodate a double ball nut setup. There are two STL files. One has a 10mm bore in the end for a 3/8th inch bearing on the end of the ball screw. The other have a 10.4mm bore for a 10mm ball screw end bearing. It's for a 16mm ball screw / ball nut, by 5mm pitch.
