Good value accessory
Simple but effective. It's not a magic fix for everything, but for anyone printing with engineering filaments, this is a must-have cheap upgrade. Keeps the heat in nicely.

Essential upgrade for consistent prints
This sleeve fits perfectly on my P1S heater block. I noticed immediately that the ambient temperature around the nozzle is more stable, which has reduced warping on my ABS prints. Highly recommended.

Perfect fit for P2S
I bought this specifically for the P2S and it matches the black aesthetic perfectly. It keeps the heat where it belongs and protects the block from accidental bumps during bed leveling.

Stable temps, better adhesion
Since installing this, my first layer adhesion has improved significantly on high-temp materials. The insulation really helps maintain the thermal envelope around the hotend.

Works well, slight fit issue initially
Does exactly what it says regarding heat retention. It was a tiny bit tight to snap on at first, but once seated, it stays put. My chamber temps are much more consistent now.

Great quality silicone
The material feels very durable and thick enough to provide real insulation without being bulky. Installation took less than a minute. No issues so far after two weeks of heavy printing.
Q: Does this come in other colors?
A: Currently, this protective sleeve is only available in Black to match the standard aesthetic of the Bambu Lab P-series printers.
Q: Will this interfere with the automatic bed leveling sensor?
A: Not at all. The sleeve covers only the heater block and does not obstruct the movement or function of the ABL sensor or the nozzle cleaning station.
Q: Is this compatible with the original P1P model?
A: This sleeve is specifically designed for the P1S and P2S models due to differences in the heater block assembly. It may not fit the P1P correctly.
Q: Can this withstand ASA printing temperatures?
A: Yes, the high-grade silicone is rated up to 300°C, which is well above the typical printing temperatures for ASA, ABS, and PLA.
Q: Do I need to remove the stock fan shroud to install this?
A: No, the sleeve is designed to snap directly onto the heater block without removing any other components or modifying your printer.
