Everyone has been wanting a halo in their printer. Now you can give your Annex K3 a Hula!

Perfect squareness, no finicky gantry squaring, 12mm belt upgrade, live shafts, and easier maintenance.

Includes:

• Hula
• 8 bearing supports
• Screws
• 4 shafts
• Spacers for shafts
• 4 closed loop 12mm epdm belts
• Pulleys
• 16 bearings

Made of the same material as your rails, eliminating bimetallic effect, heavy steel increases mass of the printer closest to where most of the motion is happening.

Rails become self aligning due to locating features in the Hula.

Removes top extrusions, gain 20mm in Z if you lost it from equipping a higher flow hotend such as Chube.

Uses the motors and rails that you have.

Compatible with stock toolhead/backer setup.

Requires long shaft motors, cannot use couplers.

Designed to be used with the following parts:

Does not include: Toolhead, rails, motors, motor mounts, hotend, or anything else not listed above.

Does not include the rail backers in this partial kit.
