Take a spare piece of PTFE tube and cut it to about 16mm.
Carve out a small notch for the 3d printed part to fit.
This may take some trial and error but make sure the PTFE tube fits snug with the 3d printed part.Install with the small notch on the left and you are good to go. Happy Printing!!
Also just curious you are using the PTFE tupe right? This is the material I shose because the filament does not stick to it and everyone pretty much has it.
Thanks, my printer just didn’t perform how I wanted it to do this little piece keeps the purge wast from coming on the bed and potentially messing up a multi color print which can sometimes me very devostating.
