Description
O-Gauge Powered Truck for 3D-Printed Locomotives
This is an O-gauge powered truck designed specifically for custom 3D-printed O-gauge locomotives. The truck is intended for use with 1:48 scale locomotives approximately 322 mm long, 68 mm wide, and 95 mm tall. The design uses commonly available bearings, and motors, making it well-suited for hobbyists building fully functional custom locomotives.
