This is a coupling ball for fort building. It will work with any round rod or dowel that is .375 in in diameter. It is also compatible with the Discovery Kids Fort Building Kit. I designed it using Onshape so if you have some rods of a different diameter you can easily change the design to accommodate. I will add a link to the Onshape file in the comments.
