Thank you for viewing! (_ _) Are you having trouble with broken or missing connecting parts? These are 3D-printed connecting parts to replace them. While we haven't lost any at home, we replaced the ones that were loose and kept falling off! These are exclusively for the E5 series Hayabusa. Please note that they cannot be attached to the E6 series Komachi. However, they can be attached to the MAX, although the tip shape is different.

Please tighten the screws gently. Don't overtighten them.
