bridge pillar for Maerklin H0 model train M tracks - scalable height

The pillar can be clamped to a Maerklin H0 M-track.
The pillars are best placed close to the connection of two tracks. This avoids tilting over the pillar when the train passes.
It worked well for me with a set of pillars differing in height by 1 cm.
The OpenSCAD file allows you to set the height of the bridge pillar. The variable x at the beginning of the file is the height in mm.

The print was made on an Ultimaker in PLA.

On request I added more stl-files. I myself printed the pillars up to a height of 8 cm. Please let me know whether the higher pillars work as well.
