2-pair, HOn3 30t Oahu Railway freight car truck. The journal lids have a raised star which was visible on my test print, but I have raised the center to make it more prominent. Designed for Kadee's 26" HOn3 wheelsets (Not included). The test print accepted these but wasn't quite free-rolling, I've revised it so that it should be so now. Available in 1, 2, and 4 pair packs. I have only tested them in FUD, and so that is the only material available for now. Wash with warm water and soap. Printing wax sometimes must be washed out with hot water.
