Thank you for viewing! (_ _) Are you having trouble with broken or missing connecting parts? These are 3D-printed replacement connecting parts. 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 x2 E6 Komachi exclusive connecting part covers x2 Exclusive connecting parts x4 (including replacements for when broken) *Couplers are 2 male and 2 female Male couplers are standard. If you comment, I can also change to female couplers, which are shown in the photos. 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. The color is the same red, but slightly different. Please consider it amateur painting. If you don't need the paint, please comment. *Even if the connecting parts break, they can be easily replaced by removing the screws. Please tighten the screws gently. They will strip easily.
