PTFE Tube Anti-Rubbing Protection Beads & Sleeves

Anyone using a Bambu Lab P/X/H printer knows the problem: the PTFE tubes slowly rub against the top glass lid until one day you notice the wear… and your print stops because the tube finally gave out. I tried the popular protection beads from other Makers, and they worked—at first. But over time…

Sobre este modelo
Anyone using a Bambu Lab P/X/H printer knows the problem: the PTFE tubes slowly rub against the top glass lid until one day you notice the wear… and your print stops because the tube finally gave out. I tried the popular protection beads from other Makers, and they worked—at first. But over time the beads drifted along the tube, letting the rubbing start all over again.
So I set out to fix the issue properly.
I designed TPU sleeves that keep those beads locked exactly where they should stay. No sliding, no drifting, no surprise wear marks. Then I went a step further and created hybrid beads with a TPU core and PETG shell—perfect for dual‑nozzle users. The TPU grips the tube, the PETG adds durability, and together they stay firmly in place.
Since using these models, my PTFE tubes haven’t rubbed once. No more wandering beads, no more tube damage. If you’ve been fighting the same problem, I hope these designs save you the frustration and keep your printer running smoothly. 😊
