E3NG (ENDER 3 NG)

Take your old, unused Creality Ender 3 and turn it into something amazing—something fast, powerful, precise, and reliable and enjoy the new level of tinkering.

E3NG is a DIY project focused on reviving up to 78%* of parts from your original printer and giving them a brand-new purpose. Many of us started with the simple Ender 3, and it taught us a lot—but 3D printing has evolved, and it’s time to step up. That’s exactly what this conversion is all about.

Originally designed for the Ender 3 Pro, it also supports other models like the V2, Neo, and even the non-Pro variant. The goal? Reuse as much as possible and build a machine that’s significantly faster, more reliable, easy to enclose, and still totally upgradable—because let’s face it, not everyone with an Ender 3 is done tinkering.

Whether you go with a low-budget build or max out performance, you’ll turn your Ender 3 into a CoreXY machine that honors its roots—while bringing it into the Next Generation of printers.

There are two versions to choose from:

  • v1.2S (standard) offers a more streamlined, kit-style approach with clear instructions and a straightforward build path—perfect if you prefer to keep things more simple.
  • v1.2 (advanced) is for those who like to go deep into the project, tweak every detail, giving you the flexibility to configure your printer to match your own preferences and setup.

“NG = NEXT GENERATION”

PRINTER FEATURES

  • Build volume (X-Y-Z): 235 x 235 x 245 mm (max Z depends on the hotend used)

  • Toolhead with 4 variants of part cooling - dual 4010, dual 4020, dual 5015, CPAP.
  • Files designed for easy printability and functionality.

OPTIONAL FEATURES (in the v1.2 - advanced)

  • Under bed fan for air circulation and faster chamber heating.
  • Active cooling for AB stepper motors.
  • Auxiliary fans with 12032 blowers.
  • Lasercut metal bed carriage for the best stability.
  • Single or triple Z stepper motors.

INTO THE PROJECT

up to 78% = Measured by weight of the parts from stock Ender 3 Pro. The percentage is calculated when reusing the majority of parts incl. motherboard, screen, screws, hotend (which is all possible). When using the required minimum of parts, 68% is reused.

For extra 9% of part reusage, there are side projects specifically designed to reuse more of the leftover parts - heat set insert press, camera slider (will be released to public later). The number of projects might grow in the future.
