I crafted this custom part specifically for my new FLSun cube printer. I have a fiberglass rod, approximately 3mm in diameter, running from one corner to about halfway across the other side near the extruder mount. My wiring harness fits on top but I wanted to reduce friction and wear so I designed this to wrap around the rod and guide the harness through it. Printing with 2.5 times each dimension for a larger size works perfectly well. To get good results, I recommend using a minimum layer time of 10 seconds or a cooling fan, along with a layer height of .2mm or less. Since the version with holes doesn't require much fill due to the added wall strength provided by the holes, it's not really necessary.
