Mainstays clothing bracket replacement

Both of my center brackets on 2 separate Mainstays brand clothing brackets failed and broke for a total of 4 brackets. so I created in Tinkercad a bracket and a sleeve for the part that broke to begin with the part fr the horizontal bar had 0 tolerance and broke the first bracket along the mid seam of layers so I printed another one and installed them with the included sleve to cover them super glued on to fix the zero tolerance issue i heated the bar with a butane torch while gently pushing it on, the ONLY play in the racks now is minor wiggle due to the tolerances on the x/y axis.
