I created this for my new FLSun cube printer. I have a fibreglass rod approx 3mm diameter going from one corner to halfway on the other side near the extruder mount. My wiring harness slides on top but I wanted to eliminate causes of friction and wear so I made this to go around the rod and to run the harness through. printing 2.5 x each dimensions for a bigger size works well. Need to print with min layer time 10sec or cooling fan and .2mm layer height or less. Not really any need for fill on the version with holes as the holes provide additional wall strength.
