This is an old-style thermistor clamping heater block for a v6 hotend. To upgrade to the newer sensor cartridge-style heater block, check out the v6 block & sock kit.
This product comes with the following items:
- V6 Heater Block (old thermistor-clamping style)
- M3x0.5x4 socket dome screw and washer to clamp thermistor
- M3x0.5x10 socket dome screw to clamp heater cartridge
v5 and v6 Heater Blocks are cross-compatible, both use an M6 thread. Note that v6 heater blocks are 0.5mm shorter than v5.
Note: This is the original E3D-V6 heater block design, not the newer design that has been updated for cartridge thermistors. Please check the related items if you're after the newer part!
