Filament guide for abrasive materials (carbon fiber) - neptune 4/3 pro/plus/max

I've been printing a lot of carbon fiber PLA/PETG/ASA and I was worried about wearing out my filament sensor so I made a replacement with a hardened bushing in it.

You will need:

1 - 5/16 x 3/16 x ¾ hardened bushing

You need to make a pause in you slicer to install the bushing. mine was at layer 111 with .2 layers. The slicer will say there is a cantilever, but that is just the designed support so you dont need actual supports.
