I had a disaster where PETG balled up on the extruder and encased my hot-end.
This melted the stock part cooling duct… so I needed a replacement.
Printing without a duct I managed to print this.
This is not tuned in any way other than to ensure it fits as a drop in replacement.
I printed it on it's back with no supports and it bridged perfectly.
Hopefully you never need this part…but if you do :) you're welcome.
