I noticed the wiring harness and filament tubes coming in close contact, particularly when the extruder head was at the extreme corners of the XY gantries.
This clip fixes the issue and is a fast upgrade to your printer without the need for supports and whatever you dial in as your run of the mill print settings.
See also a larger clip ‘Qidi Tech 1 - Cable Spacer Clip (Front)’ that can be installed near to the extruder which is the perfect paring for this as it stops bending of the harness as it enters the extruder assembly.
STL is for this larger Rear 50mm clip, but the attached Solidworks file contains configurations for both this and the Front 34mm version. Feel free to mod to suit :)
