Will buy again as needed. - So as everyone knows, there aren't any profiles for the Kobra 3 Max for larger nozzles than 0.4mm. However, it didn't take much to get these going. So far only used the 0.6mm and the prints are silky smooth even at 0.3mm layer lines. The nozzle outperforms the stock one in quality imo. I go through a kg of filament every few days so they get used quite a bit, but not a farm or anything just a hobby. Rare stringing, getting speeds around 80-100mm/s but still shaves off 1-2hours a print easy and more on even larger prints. Here are the settings I use in Anycubic Slicer Next Don't forget to go into printer settings on the actual printer and set the nozzle to 0.6/0.8. This will cause it to do a vibration calibration and PID for the new non-standard nozzle. If you don't do this it won't match the slicer profile and won't print. If you are wanting to do the 0.8mm nozzle just change the line widths to 0.82 and the two other options to 0.85 and then layer height 0.4mm plus the rest of the changes. Each new item that is different than the previous print I do a calibrate flowrate from the touch screen so don't even mess with the volume 11-12 in the settings that can be adjust but might be useful to avoid calibrating. Only have to redo it on spool/color change Process: Advanced on Layer height: 0.3 First Layer and Layer: 0.3 You can still use finer lines and could do 1st layer 0.3mm and Layer after that as 0.1mm. Which still prints surprisingly fast.

Review: ⭐⭐⭐⭐⭐ Great Upgrade – Works Perfect with Modded Elegoo CC - I used this hotend kit on a modded Elegoo Carbon Centauri and it worked perfectly. Everything fit well and installation was straightforward. One of my favorite features is the quick swap nozzles — it makes switching between different nozzle sizes fast and hassle-free. Having multiple sizes included (0.2, 0.4, 0.6) is a big plus. The hardened steel nozzles are a huge benefit. They give me the confidence to print abrasive and higher-temperature filaments without worrying about wear. Overall, a solid upgrade that performs exactly as expected. ## Features - Precision & Consistency: Engineered with a precision-machined nozzle, this A1 Mini Hot End ensures ultra-smooth and stable filament extrusion. It delivers exceptional layer-to-layer adhesion and fine detail reproduction, significantly reducing common issues like under-extrusion, stringing, or layer shifting for flawless 3D prints every time. - Wear-Resistant Hardened Steel: Made from premium hardened steel, this A2L nozzle is built to withstand the most abrasive filaments. It offers superior durability, outlasting standard brass nozzles by up to 5-10 times, making it the perfect long-term, cost-effective upgrade parts. - Leak-Free: Featuring precisely cut threads and a perfectly flat sealing surface, this replacement part guarantees a tight, leak-proof seal. This precision engineering eliminates the risk of filament oozing or clogging, ensuring consistent back pressure and reliable extrusion even during long, complex multi-hour prints. - High-Temperature: The A1 Mini Hotend operates reliably at high extrusion temperatures (up to 350°C). The A1 nozzle is fully compatible with high-performance engineering materials like ABS, ASA, PETG, PA (Nylon), and PC. It maintains structural integrity and thermal stability under extreme conditions, allowing you to expand your printing capabilities beyond standard PLA. - Quick Swap & Compatibility: Designed as a direct plug-and-play replacement, this A2L nozzle hotend is perfectly compatible with Bambu Lab A1, A1 Mini, and A2L Series hotend assemblies. No additional modifications or tools are required for installation. - Upgrade Removable Nozzle: The A1 hotend features a replaceable nozzle that has a threaded, removable hardened steel nozzle. It allows you to replace a worn or clogged nozzle in minutes, rather than replacing the entire hotend, reducing running costs. ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.2 out of 5 stars 911 Reviews | ## Images ![2 Pack 0.4mm A1 Mini/A1/A2L Hotend Kit Hardened Steel Nozzle for Bambu Lab - Image 1](https://m.media-amazon.com/images/I/61I7CV68ufL.jpg) ![2 Pack 0.4mm A1 Mini/A1/A2L Hotend Kit Hardened Steel Nozzle for Bambu Lab - Image 2](https://m.media-amazon.com/images/I/713sFJPFKfL.jpg) ![2 Pack 0.4mm A1 Mini/A1/A2L Hotend Kit Hardened Steel Nozzle for Bambu Lab - Image 3](https://m.media-amazon.com/images/I/711PWROUV8L.jpg) ![2 Pack 0.4mm A1 Mini/A1/A2L Hotend Kit Hardened Steel Nozzle for Bambu Lab - Image 4](https://m.media-amazon.com/images/I/71DooQrYazL.jpg) ![2 Pack 0.4mm A1 Mini/A1/A2L Hotend Kit Hardened Steel Nozzle for Bambu Lab - Image 5](https://m.media-amazon.com/images/I/719VcdDxT6L.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ They work, and work well!
