This 3d Printed track design is for O gauge trains. Raising the trains on the track also prevents collapsing of pickup springs over time on the shelf. There are 2 versions of the files. One set for O gauge Height Track and One set of O27 height track. There is 6mm/.25” height difference.
The files are also available on the OGR 3D printing Catalog All the files in a .zip file for download.
The track is 230mm/9” long to fit many 3D printers.
The track assembled
Use of joiners to tie the tracks together end to end is optional.
There is a counter sunk hole in the cross tie to allow it to be screwed
down.

Printing and assembly
Orientation of pieces are shown in this layout. 5 sets, 10 pieces of
each are shown.
I used a .4mm nozzle and 3-4 profile passes. The thin section of the track is optimized for a .4mm nozzle with a default .45mm print width. 2.7 mm thick. 6x.45=2.7. It takes 6 profiles exactly. When it was .24 thickness, whiskers were left on the thin section as some material pushed out. Sometimes the design needs to fit the print process.
There are 2 small tabs on the track. These go inside during assembly and slide up against the tie for easy spacing during assembly. They are 51mm/2” from the end of the track. The tie is 16mm/.625” wide.
A drop of glue can be used for assembly in the slots of the ties.
Alternatively, the width of the track could be increased 1-4% in the
slicer to make a press fit.
The joiners are a tight press fit to the holes in the track. Glue should
not be needed.
