The CHCB-OT hotend is a result of a collaboration between Omranello and TriangleLab to bring you a drop-in replacement hotend that brings greater flow rates and reliability to the K1 and K1 Max system.

Some changes/improvements:

• Planar contact heating element has better contact than ceramic heating ring contacts

• Compared to the original OT hotend heating elements and thermistors are easier to maintain and replace

• 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.
• Compatible with various MK8 series nozzles that are readily available.
• Drop-in replacement for the hotend of the Creality K1 /Creality K1 MAX
