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 E6 Komachi. Please note that they cannot be attached to the E5 series Hayabusa. Set Contents: E6 series Komachi exclusive connecting parts x1 E6 Komachi exclusive connecting part cover x1 Exclusive couplers x2 (including replacements for when broken) The couplers are basically the male type. If you leave a comment, I can also change them to the female type couplers shown in the photos. Please feel free to ask (*_ _) One male and one female are also possible. If you want spares, please comment. You can add them for 30 yen each, regardless of male or female. *Vehicles are not included in the set. Please prepare them yourself. The color is the same shade of red, but slightly different. Please consider it as amateur painting. If you don't need the paint, please comment. *The material color before painting is different from the photo. *Even if the connecting parts are damaged, they can be easily replaced by removing the screws. Please tighten the screws gently. They will strip easily.
