Brass Heated Block for CR-10 Printers

This brass heated block is designed for CR-10 3D printers and similar all-metal hotends. It serves as a direct replacement part for maintaining or upgrading the extruder assembly. The component is manufactured from premium brass for high temperature resistance and extended service life. Machined with high precision, it has been tested for reliable high-temperature printing performance.

M6 and M3 Threaded Mounting Holes

The block features an inner hole for set screws with M6 and M3 threads to secure the heater cartridge and thermocouple. It accepts a 6 mm diameter heat pipe and a 3 mm diameter thermocouple for standard sensor installation. The nozzle interface uses M6 threads for compatibility with matching extruder nozzles and heat-insulated components. These specific thread sizes determine whether the block fits your existing hotend configuration.

Brass Construction Handles Sustained Heat

Premium brass construction provides consistent thermal conductivity during extended printing sessions. The material resists deformation at elevated temperatures required by high-temperature filaments. Precision machining ensures tight contact between the block, heater cartridge, and temperature sensor for stable thermal control. The compact 20x20x10 mm form factor integrates into standard CR-10 hotend assemblies without modification.

Questions about this item

How does the 20x20x10mm size affect fit inside a CR-10 hotend?

The block matches the standard CR-10 heater-block footprint, so it seats directly in the existing mount without adapter plates or spacing shims.

What does the M6 nozzle thread and 6 mm heat-pipe bore mean for compatibility?

M6 threads accept any standard CR-10 nozzle, while the 6 mm bore fits the stock heat-break and 3 mm thermocouple hole without re-drilling.

What physical clearance does the brass block need for mounting?

Allow roughly 20 mm square by 10 mm tall plus room for the M6 nozzle, 6 mm heat-break and M3 set-screw access on the side.
