Half-size track I printed misses dimension of joints by far, see attached picture. Note that general dimensions are ok, e.g. crossties has same width in printed and genuine brick, meanwhile joint ball/hole of printed one is too short to match original brick and there is no way to latch them.

Interesting. Haven't seen brown rails. I have gray ones, and they fit pretty much perfectly, to allow some minimal play, just like original ones. Maybe my printer calibration is quite off, but this looks to be too much.

I have attached SCAD files. Looks like you need to adjust "to_center" variable in "Tooth" module (line 25) to align with your version of the rails.

Do not forget that these tracks are really simplified : they do not allow to plug bricks at the bottom, which is quite sad...

Yes, correct. They are focused on ease of printing, rather than compatibility. There are a few designs that are brick-compatible. I printed a bunch, but they are pain to get first layers to stick well for me.
