Train track, 180 Degrees turn, female-female

Hi all,

I just started using 3D printers a few months ago and train tracks is a regular print request I get from friends and family.

Inspired by Janne's work, I did a remix using openscad and created a female-female version of an 180 turn track, as I felt that the male-female was limiting the option of this idea. Essentially, I split the track in half, got rid of the male side, duplicated and mirrored the female side and pieced them together.

I love using Fresco's Brio Connectors, as these don't only connect the two pieces, but they pull them together, resulting in a tight connection.
