Needed a clean way to mount several bits of electronics for my air handlers.  These make use of the threaded rod already in place and give me a flat surface to mount things to.  I used a mix of 3M velcro tape and zip ties.

The segmented version may be slightly easier to clip onto the rod, at the sacrifice of a little less strength.

These are surprisingly strong.  Printed in PETG, 0.2mm layer height.
