Improved temperature stability
Noticed less fluctuation in nozzle temperature during prints. Very easy to install, just slide it on.

Peace of mind
As a beginner, I was worried about touching the hot block. This cover solves that problem completely.

Perfect fit for A1
Does not interfere with the part cooling fan or probes. Highly recommend for all A1 owners.

Good quality silicone
Material feels durable and heat resistant. Took a little effort to snap into place but stays secure.

Essential safety upgrade
This sleeve fits perfectly on my A1 mini. It keeps the heat concentrated in the hotend and prevents accidental burns during maintenance.
Q: What is the maximum temperature this silicone can withstand?
A: The high-temperature silicone is rated to withstand continuous exposure up to 260°C safely.
Q: Does this affect the part cooling performance?
A: No, the sleeve only covers the heater block and does not obstruct the part cooling fan airflow.
Q: How often should I replace the silicone sleeve?
A: Inspect regularly for cracks or wear. Replace if damaged to ensure continued thermal protection and safety.
Q: Is this compatible with the standard A1 and the A1 mini?
A: Yes, this silicone sleeve is designed to fit both the Bambu Lab A1 and A1 mini printer models.
Q: Do I need to remove the nozzle to install this?
A: No, you can install the sleeve directly over the heater block without removing the nozzle or hotend assembly.
