Thank you for purchasing our Heat Block & Nozzle Conversion for Elegoo Centauri Carbon to allow use of Bambu Labs A1 and H2 series quick change hotends on your Elegoo Centauri Carbon. This product is a heavily modified derivative of the original model created by @Pedrinbeep at https://makerworld.com/en/models/1993997 With his permission, we began from his provided original CAD model and re‑engineered the design extensively to improve dimensional accuracy when printed in PPA‑CF, enhance overall fitment, simplify installation, and streamline the manufacturing process. While the geometry is based on his original concept, the final design reflects significant structural and functional changes exclusive to our design.

The video excerpt below, taken from Pedrinbeep’s original demonstration, shows the basic installation workflow.
If you purchased only the PPA‑CF adapter (without our heater assembly), you can view the complete upgrade process—including transferring the thermistor and ceramic heater—in Pedrinbeep’s full original video: https://youtu.be/4X3NquYXHjs?si=ZdLV2bNtl7VGgaAy)

🌡️ What temperature does the bracket actually see — and why doesn’t it need to be metal?

Our brackets are printed in PPA‑CF, an engineering‑grade high-temperature nylon reinforced with carbon fiber. After printing, the part is then fully annealed. With annealing, this material reaches a heat deflection temperature of ~200 °C, which is far beyond anything the bracket experiences in real use.

Even though the hotend can reach 350 °C, the bracket is never exposed to that temperature. Here’s why:
Even though the hotend can reach 350 °C, the bracket is never exposed to that temperature. Here’s why:
- A zirconia insulating block sits between the heater block and the bracket
- The bracket is mounted ~5 mm away from the heat source behind the zirconia insulating block
- The hotend fan and part cooling fan constantly move air across the area
- The printer is not operating in a 90 °C heated chamber
Because of this thermal isolation, the bracket only sees:
Because of this thermal isolation, the bracket only sees:
- 70–110 °C during normal printing
- Up to ~120 °C during long, enclosed prints
These temperatures are far below the ~200 °C heat resistance of annealed PPA‑CF.

🔧 A metal bracket simply isn’t necessary — the material we use is already engineered for this environment. It won’t soften, warp, or deform, and it avoids the vibration‑related cracking that thin aluminum adapters can experience.
