Artillery Sidewinder X1 extruder filament guide. My PTFE tube may move inside the original extruder filament guide, resulting in clog right before the heat break, which gave me a headache with underextrusion issue. My version of extruder filament guide has a stopper inside it so that it could prevent the PTFE tube from moving. However, you need to cut your PTFE tube precisely at 44.0mm or else it does not fit into the printer. This STL has to be printed upside down to ease the process of removing support or else the supports will be inside of the filament guide, which I think might be hard to remove it. If there is request to do another version with chamfer, do let me know.
Lastly, please do tip me even if just $1 if you feel that this helped you out! It means a lot to me and I will share more functional design in the future! Thank you very much guys!
