Product Description


Hi everyone, I'm currently working on developing tooling to injection mold these tracks.  However, that's not an inexpensive endeavor, so I want to make sure I get this right.  I've posted the models here for those that would like to help beta test these tracks before going into production.  Your support and feedback will help make this and the 9V versions a reality.  I have models of the corresponding switches I will post soon as well; there's just a few bugs I have to work out to make them more amenable to 3D printing.


This model is for a 72 stud radius (22 11/16" / 576mm) curve for Lego trains.  Track segment is compatible with standard 9V and PF track pieces, including the flex-track.  Curve angle is 22.5° (8 pieces per half-circle).
