Build info on my blog (link below). These pieces make up printable LED lenses for the rear tail light and side markers for the Segway Ninebot Max e-scooter. They should fit all of the G-series models but suggest measuring. Each has various pieces: The lens portion should be printed in clear, while other bits in black or any colour you wish. For the lenses, opaque is good too as it will diffuse the LED effect so the individual pixel light blends together. File settings are default and require verification.
