The design was initially inspired by the metal face bolt of Beyblade Metal Fusion. However, I have added some different patterns that I personally like, and I will continue to update with new designs in the future ( mainly because drawing takes time ). The face bolt itself is based on AronDS's project ( by the way, really awesome 3D file). Although there are slight differences in the shape of the face bolt, it has been tested and matches quite well on most of the Beyblades.
Also, make sure you are using a "resin printer' instead of FDM one because I don't think FDM printers allow you to print this kind of fine pattern, but I would like to know if anyone got a successful print.
