Basic 3 plank wagon for OO scale.
Suitable for Hornby / Bachmann 12.6mm standard wagon wheels and axles.
Comes with a NEM pocket at the standard height and distance to the buffer beam.

Depending on your printer, it may require a little further drilling of the axleboxes for your wheel axle set. I printed in ABS-Like resin, which worked well straight out of the printer. If you do need to drill a little more, use a 2.5mm drill bit.
