In a quest to try and minimise the chance of the PFTE tube and extruder cable from rubbing on the x-rail upper carbon rod, I created a guide ramp (see my other models) and modified the passthrough so it forces the PFTE tube slightly upward. It works well on mine, you may have to tweak the length of the tube and/or use a different extruder guide.

The passthrough uses the same heat set inserts as the original.

I've also made a ramp to help guide the tube and cable set further away from the x-rail, which is worth a try.

Happy to hear if it works :)
