A bit of a "fun" track section. I Had the idea from old and odd tracks I've seen, with various odd track sections, like grass, sand, or even water. So I thought how could I allow for those options within the track I've already designed. This is the first version. the track is 250mm long with a 113mm wide, 7.5mm deep section for adding "Fun" like sand, gravel, or plastic grass. Depending on your print settings you could maybe even do water, however there is no ramp to allow the cars to easily roll back up out of the depression, so you will need to allow for that with your fillings. Files are provided in both stl and step versions. You will need to print 2 transitions as the track bed is raised to allow for the insert section.
