Made my first nozzle change easy

As a beginner, I was terrified of breaking my printer head. This tool made the process straightforward and gave me confidence. Instructions could be clearer, but the design speaks for itself.

Essential tool for any 3D printer owner

This little tool has saved me so much time. Changing nozzles used to be a struggle with pliers, but the Crab tool grips perfectly without stripping the hex. Highly recommended for Ender 3 users.

Good value for money

For the price, you really cannot beat this. It simplifies maintenance significantly. I deducted one star only because the included pouch is a bit flimsy, but the tool itself is solid.

Works great, slightly tight fit initially

The build quality is excellent. It was a bit stiff when I first tried to slide it over the heater block, but after a few uses, it works like a charm. Much safer than using an open-ended wrench.

Precision engineering

Finally, a tool designed specifically for this purpose. The socket depth is perfect for reaching recessed nozzles. It prevents damage to the heating element wires which happened to me before.

No more burnt fingers

I love that I can change hotends quickly without worrying about slipping and touching hot components. The grip is secure, and the metal feels very durable. A must-have accessory.

5 FAQ

Q: Will this fit a Mosquito hotend?

A: The tool is optimized for standard V6 geometry. While it may fit some variants, it is not guaranteed to work perfectly with non-standard hotends like the Mosquito without modification.

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

A: Yes, the BIQU Crab tool is fully compatible with the Ender 3 V2 as it uses standard V6 style hotends and nozzles.

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 slightly or using heat-resistant gloves to prevent accidental burns during maintenance.

Q: What is the warranty period for this accessory?

A: The BIQU Crab Tool comes with a standard 1-year manufacturer warranty against defects in materials and workmanship.

Q: Does this work with hardened steel nozzles?

A: Absolutely. The tool is designed to grip the hexagonal base of the nozzle regardless of the nozzle material, including hardened steel, brass, or stainless steel.
