Essential tool for hotend maintenance
This little tool saves so much time when changing nozzles. The grip on the heating block is secure and prevents stripping the screws. Highly recommended for any 3D printer owner.

Simplified my workflow
Keeping this next to my printer at all times. It makes cold pulling and nozzle changes incredibly fast. The metal is thick and doesn't bend under pressure.

Precision engineering
The machining quality is excellent. It fits standard V6 style hotends without any wobble. Makes swapping between different nozzle sizes a breeze during testing.

Works great but tight fit initially
The tool works exactly as described. It was a bit tight to fit over my specific heating block at first, but after a few uses, it slides on perfectly. Very sturdy construction.

Good but not for all blocks
Works well on my Ender 3, but didn't fit the custom aluminum block on my older printer. Check your heating block dimensions before buying. Otherwise, good quality.

No more burnt fingers
I used to use pliers which always slipped or scratched my block. The Crab tool holds the hex nut perfectly while I unscrew the nozzle. A must-have accessory.
Q: Can I use this tool while the hotend is still warm?
A: While the tool is made of metal, we strongly recommend allowing the hotend to cool down completely before performing maintenance to avoid burns.
Q: Does this tool work with the Creality Ender 3 V2?
A: Yes, the BIQU Crab tool is fully compatible with the standard V6 hotend found on the Ender 3 V2.
Q: What is the exact hex size this tool accommodates?
A: The tool is designed to fit the standard 7mm hex nut typically found on V6-style heating blocks.
Q: Does the package include a wrench for the nozzle itself?
A: No, this package includes only the Crab socket tool for holding the heating block. You will need a separate small wrench or socket for the nozzle.
Q: Is this tool compatible with all-metal hotends?
A: Yes, as long as the heating block has the standard hexagonal shape and dimensions, it will work with both brass and all-metal hotends.
