- Compatible with Creality Ender 3 series and CR 10 printers
Who it fits
Good fit for
You should buy this kit if you own a Creality Ender 3, Ender 3 Pro, Ender 3 V2, Ender 3 Max, Ender 5 Pro, Ender 3 S1, Ender 3 S1 Pro, Ender 3 Neo, or any CR 10 Series printer. It is ideal for users who print with 1.75 mm PLA or ABS filament regularly. The inclusion of cleaning tools and a storage box makes it perfect for those who want to keep their workspace organized. You will appreciate the precision engineering that minimizes the risk of leaks and clogs during long print jobs.
Who should skip it
You should look at another option if you need nozzles for a different thread size or diameter. This kit only contains 0.4 mm nozzles, so it will not work for high-speed printing with larger apertures or detailed miniatures requiring smaller holes. It is also not suitable for printers that do not use MK8 style hotends, such as those from other brands with proprietary connections. If you do not have a storage box or need to organize your tools, the included box is basic and may not meet your specific organizational needs.
Verdict: This kit offers essential specs for maintaining standard FDM printers, including precise nozzles and necessary tools. It is a solid choice for owners of compatible Creality machines who value convenience and reliability.
Comgrow Nozzle Kit Key Specs
Primary Material: Brass
Brass offers excellent thermal conductivity, allowing the hotend to heat up quickly and maintain stable temperatures. This material is soft enough to be easily cleaned with brass brushes but durable for standard filaments. It is the industry standard for hobbyist printing, making it a safe choice for most users who print with PLA or ABS. It balances cost and performance effectively for general-purpose builds.
Nozzle Diameter: 0.4 mm
A 0.4 mm tip is the most common nozzle size, suitable for layer heights between 0.1 mm and 0.28 mm. It provides a good balance between print speed and fine detail resolution. This size handles standard filament flows well, reducing the risk of clogs while still producing smooth surface finishes. It is the ideal default for beginners and experts alike, ensuring compatibility with most slicer profiles.
Extruder Nozzle Diameter Error: Less Than 0.02 mm
This tight tolerance ensures consistent filament flow with minimal variation between nozzles. A deviation under 0.02 mm reduces the risk of leaks and ensures uniform extrusion, leading to stronger layer adhesion and fewer print failures. This precision is critical for users who require repeatable results across multiple prints. It indicates high manufacturing quality, helping you avoid issues caused by inconsistent nozzle bores.
Input Diameter: 1.75 mm
This specification confirms the nozzle accepts standard 1.75 mm filament, the most widely used diameter in FDM printing. It ensures compatibility with the vast majority of hobbyist filaments, including PLA, ABS, PETG, and TPU. You do not need to worry about fitting issues with your extruder system. This standard size simplifies material selection and ensures the nozzle works seamlessly with popular printers like the Creality Ender series.
Design and Build Quality
According to the listing, this kit uses premium brass for the nozzles. Brass provides good abrasion, heat, and corrosion resistance. You can replace nozzles quickly to maintain print quality. The smooth inner wall and an extruder diameter error of less than 0.02 mm help reduce print head leaks. This precision avoids common nozzle clogging issues during operation.
The package includes twenty-five 0.4 mm nozzles. It also provides ten stainless steel cleaning needles, one hexagon wrench, and stainless steel tweezers. The needles have good toughness and do not break easily. You can clean the nozzle from multiple angles using these tools. The included hexagon wrench simplifies nozzle adjustment. All items fit into a storage box for easy carrying. This layout keeps small accessories organized and prevents loss.
Wide compatibility is another design feature. The nozzles fit Creality Ender 3, Ender 3 Pro, Ender 3 V2, Ender 3 Max, Ender 5 Pro, Ender 3 S1, Ender 3 S1 Pro, and Ender 3 Neo printers. They also work with CR 10 Series machines. The kit is suitable for all 1.75 mm PLA and ABS filaments. This broad support means you do not need separate parts for different models. The design prioritizes practical use and easy maintenance for standard 3D printing tasks.
Setup And Daily Use Guide
Installing these nozzles requires basic tools included in the box. You will use the provided hexagon wrench to remove the old brass nozzle from your hotend. The kit includes a stainless steel cleaning needle to clear any residual filament from the heat block threads before inserting the new part. This step ensures a tight seal and prevents leaks during printing. The smooth inner wall design helps reduce friction, allowing filament to flow consistently through the 0.4 mm opening. You can use the tweezers to handle the small nozzles safely, keeping your fingers away from hot surfaces. Once installed, the nozzle is ready for standard 1.75 mm filaments like PLA and ABS. The listing states the diameter error is less than 0.02 mm, which implies consistent extrusion and reduced risk of clogging. This precision supports reliable daily printing without frequent adjustments. The storage box keeps the extra nozzles and tools organized, making it easy to swap parts when needed. The kit is compatible with Creality Ender 3 series printers, including the V2, Pro, Max, S1, Neo, and CR 10 models. It also works with any 3D printer using MK8-style hotends and 1.75 mm filament. You do not need special software or drivers. Just mount the nozzle, calibrate your Z-offset if necessary, and begin printing. The high abrasion and heat resistance of the brass material mean the nozzles withstand repeated heating cycles. This durability supports long-term use for hobbyist projects. The included cleaning needles allow you to maintain the nozzles by clearing minor blockages from multiple angles. This feature helps extend the life of each nozzle before replacement is required.
Before You Buy This Kit
You should verify your printer model before purchasing. This kit lists compatibility with Creality Ender 3 series and CR 10 series printers. Ensure your machine uses the MK8 hotend standard. If you print with abrasive filaments like carbon fiber, brass may wear faster. You might want steel or hardened steel nozzles for those materials. Keep your storage box handy to organize the twenty-five nozzles and tools. The included cleaning needles help maintain flow, but you may need spare filaments for testing new settings. This option sits alongside other hobbyist upgrades in our 1 product guide. It suits users who prefer standard brass for general PLA and ABS prints. Check your hotend temperature range matches the nozzle specifications. Regular replacement keeps print quality high. This kit provides a straightforward path to maintaining your printer without complex modifications.
Check before you buy
- Confirm your printer uses the MK8 hotend standard.
- Check compatibility with your specific Ender or CR 10 model.
- Verify you are using 1.75mm filament for this kit.
