About this 3D model

As a kid I loved NITROME games, I was reminded of one of them recently where you play as a couple of cactuses and navigate a course The game is linked below: http://www.nitrome.com/games/offtherails/#.XaYKoJNKgWo If you don't know the game it's just a fun print of a couple of cactuses on a railway. The model is meant to run on HO/OO gauge wheels which give it an On30 feel. If anyone prints it for use with O gauge track.
