Is this Comgrow 3D printer upgrade kit safe to use?

Yes, this kit is designed for safe operation within standard 3D printing parameters. The components are made from durable materials like metal and PTFE, and are intended to improve the reliability of your existing 3D printer setup. Always follow general 3D printer safety guidelines, such as ensuring proper ventilation and handling hot components with care.

How does this kit improve print quality?

The all-metal extruder provides a firmer grip on filament, reducing slips and enabling faster, more consistent extrusion. The Capricorn Bowden tube's tight tolerances ensure filament is guided precisely to the hotend, minimizing errors. Combined with stable bed leveling from the firm springs, these factors lead to smoother prints with fewer failures.

Will this kit fit my specific 3D printer model?

This kit is designed for wide compatibility with Creality printers, including Ender 3, Ender 3 Pro, Ender 5 Pro, Ender 5 Plus, CR-10, CR-10S, CR-6SE, Ender 6, and Ender 7. It directly replaces the stock plastic extruder and uses standard fittings. Please verify your printer's hotend and extruder mounting style matches the MK8 extruder and Bowden tube setup for optimal fit.

What is the benefit of Capricorn Bowden tubing?

Capricorn XS Bowden tubing is regarded as the highest quality PTFE tubing in 3D printing due to its tight internal tolerances. This ensures filament is guided directly to the hotend with minimal room for error, reducing extrusion issues. It also withstands higher temperatures, making it suitable for printing filaments like ABS and Nylon.

How do the bed-leveling springs help?

The extra-firm Creality die springs are more resistant to compression loss than standard springs. This helps maintain a consistent bed level for more prints, reducing the frequency of manual bed adjustments and contributing to more reliable first layers and overall print success.

Can I use this kit with different filament types?

Yes, the Capricorn Bowden tube is rated for high temperatures, making it perfect for printing various filaments including PLA, PETG, ABS, and Nylon. The all-metal extruder is also robust enough to handle these materials effectively.

What is included in the Comgrow 3D printer upgrade kit?

The kit includes an all-metal MK-8 extruder feeder, 1 meter of Capricorn XS Bowden tubing, extra-firm Creality die springs, and PC4-M6 & PC4-M10 pneumatic fittings. All necessary screws and parts for assembly are also provided.

Key Features

3D Printer Extruder - Instantly provide improved print quality and reduce filament slipping by firmly grasping the filament between two threaded wheels locked together. No more skipped steps when extruding at high speeds or after retractions. Print faster with this superior design, which is able to feed much more filament into the hotend in the same period of time than stock plastic extruders.
100% Original Capricorn XS Bowden Tube for 1.75mm filament - Capricorn ptfe tube is regarded as the highest quality PTFE tubing in all of 3D printing. The tight tolerances make sure that the filament is lead directly to the hotend with as little room for error as possible between the extruder and the hotend. It is rated for withstanding the highest temperature in the market which is perfect for printing filaments such as PLA, PETG, ABS, Nylon. Fits for 1.75mm 3d printer Filament.
Creality Die Springs - Those springs are extra firm and help to hold the bed level for longer while being more resistant against wearing out and loosing compression. Level the bed once and it should hold for more prints with these high performance stiff springs. PC4-M6 & PC4-M10 pneumatic fittings are also included for replacement use on any stock creality hotends.
Easy to Assemble--- Our ender 3 extruder and 1 meter capricorn tubing includes all the necessary screws & parts needed, it can directly replace your old original fragile plastic extruder. You can assemble it quickly by viewing the assembly diagram.
Wide Compatibility - The Creality ender 3 upgrades kit can used on other creality 3d printers, like CR-10/ CR-10S / CR-10S Pro/ CR-6SE/ Ender 3 / Ender 3 Pro /Ender 5 / Ender 5 Pro/ Ender 5 Plus/ Ender 6/ Ender-7.

Why choose this product

Superior Extrusion and Bed Stability

This Comgrow kit addresses common 3D printing frustrations by upgrading critical components. The all-metal extruder ensures a consistent, firm grip on filament, eliminating skips and enabling faster printing speeds. Paired with the renowned Capricorn XS Bowden tube, known for its tight tolerances and high-temperature resistance, filament is guided precisely to the hotend. This combination significantly reduces print failures caused by filament grinding or inconsistent flow. The extra-firm bed leveling springs provide a more stable build platform, holding level for more prints and reducing the need for constant recalibration. This upgrade is designed for users seeking to improve print quality and reliability.

Who Should Upgrade and Who Should Consider Alternatives

This kit is ideal for owners of Creality Ender 3, Ender 3 Pro, Ender 5 Pro, CR-10, and similar printers looking to overcome filament grinding, extrusion issues, or bed leveling problems. If you frequently print with materials like ABS or Nylon that require higher temperatures, the Capricorn tube is a significant advantage. Users experiencing frequent filament jams or inconsistent extrusion will benefit most. Those with direct drive extruders or printers not listed in the compatibility range should seek specific upgrade kits for their models. Beginners should review assembly guides carefully, though the kit is designed for straightforward installation.

How to use

Carefully detach the old plastic extruder and Bowden tube from your 3D printer's hotend and filament path. Disconnect any wiring associated with the extruder motor. — Remove Old Extruder and Tubing
Mount the new all-metal MK-8 extruder feeder onto your printer's frame, ensuring it aligns correctly with the stepper motor. Secure it with the provided screws and reattach the motor wiring. — Install New All-Metal Extruder
Install the Capricorn Bowden tube, securing it with the new pneumatic fittings (PC4-M6/M10) at both the extruder and hotend ends. Replace the old bed springs with the new firm springs, adjusting for initial bed leveling. — Connect Capricorn Bowden Tube and Springs
Perform a full bed leveling procedure. Calibrate your extruder's E-steps if necessary. Load filament and run a test print to ensure smooth extrusion and proper adhesion. — Calibrate and Test Print
