Description

The Trianglelab CHCB-OT Hotend is designed for optimal performance with K1, K1 Max, Ender 3 V3 KE/SE, V3, V3 Plus or the Sprite printers. This hotend features better reliability and ease of repairability compare to stock hotend. It also have open nozzle system, allow you use any MK8 nozzle. 

Note 1: Ensure you double check your K1/K1 Max, as some newer unit from 2024 are shipping with integrated(unicorn) nozzle/heat break. If that is case, select the "OTC" versions. 

Note 2: Newer batch (OT/OTC for K1 Series) will require you de-solder/re-solder the thermistor head (JST Header provided) and/or re-pin connectors to suit older PCB, if you're running older PCB Version or switch to newer 2025 PCB, (Order from 17/05/2026) and you require a heater adapter wire, or you will need cut existing housing to fit.

Through a remarkable collaboration, Omranello's visionary insights and TriangleLab's engineering prowess converged to craft the exceptional CHCB-OT hotend, redefining possibilities in 3D printing technology. Omranello + TriangleLab is proud to introduce our newest CHCB-OT to the community, enhancing the capabilities of Creality Printers.

Features: 

  1. Planar contacts heating element have a more certain contact than ceramic heating  ring contacts
  2. Compared to the original, the OT/OTC hotend heating elements and thermistors are easy to maintain and replace, you can replace each component at time, compare to whole hotend assembly and reduce future maintenance cost.
  3. Separate design of fixed flange and heating core. The flange is made of a material with a low thermal conductivity to reduce the working temperature of the heat sink fixed with it by screws.
  4. Compatible with MK8 series nozzles, allow unified nozzle open sourced system with other Creality Printers. We recommenced pairing with Bontech CHT for higher flow.
  5. Drop-in replacement for the hotend of the Creality K1 /Creality K1 Max(2023) and CR-Sprite Hotend Printer. [Ensure you have selected correct selection] Note: For CR-M4, please select K1. [If un-sure please check listing photo of the connector size for your breakout board for your printer]
  6. Can be direct installed on Creality Sprite Extruder to increase flow rate by approx. 20-50% depending on nozzle size/filament and printing conditions and may require additional tuning.
