Hot end Spacer. I made in Tinkercad. Fits over ptfe tube

thingiverse

I made this is tinkercad, it fits over the ptfe tube. you dont have to worry bout the bushing being off center like the original. they fit snug with every filament so far except once they were a little loose, not sure if i didnt have enough squish or the filament was silk? but they fit fine 99.9 percent of the time. increase flow if its loose. i have a special way i put this together too. they never leak. works great.
