Works with the PicassoTiles race track set. This track piece will fit on the normal support towers and stay in place using the little pins that hold it together with no issues. However, laying this track on the floor will require clips to hold the pieces together (see photos). This is because the normal pieces have magnets in them to hold them together.
Print a few of these clips to keep the track together: https://www.printables.com/model/839399-picassotiles-track-clips
This track printed fine at 10% gyroid infill and is still remarkably strong to hold up to little kids' play. Unnecessary material has been removed so the print time is reduced.
The author marked this model as their own original creation.
