train rails

Dimensions are not a standard like H0 or 0 format. It's for my dauhther train that does not respects any standard scale.

See the dimmemsion.png file

It's a work in progress... I'll add crosses, switches etc... Most recent version is probably on my Github repository https://github.com/gnieark/rails

The two files adaptateur2.stl and adaptateur.stl exists because on a previous version the hooks on all rails were not centered. It's fixed now
