Top hat grommet / cone for Prusa Core One INDX Top Hat holes.
Super thin 0.4mm & flexible, articulates and does not impede PTFE filament tube.
Printed in 95A TPU.
Ensure supports completely removed.
Super fiddly to install until technique establised (last three of 8 :)), warm grommet cone by kneading between thumb and finger. Push cone through from inside and slightly pull from outside, then push one side of the lip seal through from inside, and rotate from inside until seals are correctly in place both sides.
