Joiner for Closetmaid hanger rods

thingiverse

I had to use two separate pieces of Closetmaid brand 3/4" hanger rods in my closet and need to join them together. This joint fits snugly inside each rod end. 6.4mm (1/4") length between ends of rods. Flat side is to allow printing on its side without support and to ensure the filament grain direction is normal to the shear direction. I printed at 0.1mm layer height. I wasn't worried about infill. I kept it at 20%. I suppose the more the merrier.
