Finally got the print settings dialed in for the rod holder.  In the future i'd like to test PLA as a bearing material.  I tried nylon, but it was rather soft.  Igus has some special filament that seems interesting.

This design was so that I didn't have to "dial in" on a 1mm print nozzle.  I could get the majority of the structure there and print a more precise bushing with a 0.4mm nozzle.
