Test lead / cable hanger for HDX wire shelving

All of the test lead hangers I've seen so far want to be mounted on a wall, and give you a fixed quantity of slots to hang cables from.  I wanted to customize how many slots I got, and I wanted to attach it to some wire shelving that I have, so I modeled this up.  It clips to the edge of some HDX wire shelving, and hangs off the side; you can clip it either to the front or to the side.  My wire shelving seems to use 7/16" main tubing, and this attaches with a satisfying “click!” to that.  A dovetail joint on the back provides lateral support between neighboring hangers.

I managed to cram 12 of these on a build plate on my Bambu X1 Carbon.  I used some Hatchbox PLA but I'm sure any PLA would probably work fine.  There is an obvious orientation to print it in (flat side down); print it like that.  My printer seemed to have no trouble with the bridges on default settings at 0.20mm layer height, but if you have a different printer, you presumably know its capabilities better than I do.
