Curtain rod adapter

With many curtain rods, there are 2 sliding sections that allow the rod to be adjusted in length.  The problem comes when you go to pull your curtains across the rod and they get hung up and stuck on the joint.

This adapter fits snugly on the most common sized curtain rods.  The inner dimensions of the 2 sides are 16mm and 19mm.  You may have to scale up or down by 1% or so depending on the accuracy of your printer. If you print with the sharp edge downward, you should not need supports as long as you use a brim.
