I created this model after a small piece of fiberglass tape was dragged into the extruder resulting in a gnarly clog. The small hole allows the start of the filament to be anchored without tape.
printed in periwinkle Hatchbox pla.
Easy print, printed fine in sport mode. very smooth model. fits right on the spool with no issues.
will add details once I use it with a respooling machine.
