OO Gauge Model Railway wheels for wagons and coaches. These are the standard 14.5 mm gauge for OO, they will fit into most coaches and wagons that have pinpoint axles. These come pre supported for a resin printer and feature thin supports to allow for easy removal. These are recommended to be printed on a resin 3d printer as this will allow a smooth surface. If they are resin printed a tough resin should be used for example Sunlu ABS like or ELEGOO ABS like.
