Precision engineering at a low cost

I appreciate the dual-sided design. One side for the nozzle and the other for the heating block. It prevents rounding off the hex nuts which was a frequent issue for me before.

Made my first nozzle change easy

As a beginner, I was terrified of changing my nozzle. This tool made the process straightforward and gave me the confidence to maintain my printer properly. Great purchase.

Essential tool for any 3D printing hobbyist

This little tool has saved me so much time. Removing hotends used to be a struggle with pliers, but the Crab tool grips perfectly without slipping. Highly recommended for Ender 3 owners.

Bought five for our lab

We equipped all our workstations with these. They are durable enough to withstand daily use by students and significantly reduce the risk of damaging printer components during maintenance.

Works great, slightly tight fit initially

The build quality is excellent. It was a bit stiff when I first tried to use it on my nozzle, but after a couple of uses, it works like a charm. Much safer than using adjustable wrenches.

Good value, wish it came with a case

The tool itself is fantastic and does exactly what it says. My only minor complaint is that it doesn't come with a small protective pouch, so I had to find my own storage solution.

5 FAQ

Q: Does this work with hardened steel nozzles?

A: Yes, the socket is designed to grip the hex flat of the nozzle regardless of the nozzle material, including hardened steel, brass, or stainless steel.

Q: Can this be used while the hotend is still hot?

A: While the tool is made of metal, we strongly recommend allowing the hotend to cool down to a safe handling temperature before performing any maintenance to avoid burns.

Q: Is there a left-handed version available?

A: The tool is symmetrical in function and does not require a specific handedness; it can be operated comfortably by both left and right-handed users.

Q: What is the return policy if it doesn't fit my custom rig?

A: We offer a 30-day return window for unused items in original packaging. If it doesn't fit your specific setup, please contact our support team for assistance.

Q: Is this tool compatible with the Creality Ender 3 V2?

A: Yes, the BIQU Crab tool is designed to fit standard M6 nozzles and heating blocks found on the Ender 3 series, including the V2 model.
