If you do plan to replace it try the CHCB-OT hotend. Whichever one you end up getting remember to heat it up and screw the nozzle in while hot. I had them leak (between the nozzle and the rest of the hotend) if I didn’t do so.

Didn’t have any issues with deforming of PETG parts in my car. Yeah, -CF should be handled with care, but there are parts that you might not need to touch, and it will be a bit more resistant to deforming under heat.

Try PETG or PETG-CF

Then it might be flow or inconsistent extrusion. Try doing calibration available in Orca (probably same thing in Bambu slicer).

Looks like the nozzle is too close (z-offset is wrong) or too much filament is extruded (flow rate is too high).

Of course. One can make a better knife, or just take one out of a kitchen drawer.
