The improved version of the roads to assemble for children to play with toy cars.

With the first results being conclusive, I am launching an improved version of my roads.

The New Specifications

Realization

The steps are (almost) the same as for v1. The differences are as follows:

Hermaphroditic Tabs

For the tiles to hold together, I need tabs like those on puzzle pieces, for example. But there are two major drawbacks to this male/female system of puzzle pieces:

  1. You cannot rotate a tile to use it in the other direction: male/male or female/female does not work.
  2. If you introduce "branch" tiles, you will probably end up wanting to connect two males or two females: a male/male or female/female adapter will be necessary.

However, an advantage is that you can flip (front/back) the tiles to change the direction of a turn, for example, but in this case, it must be printed on both sides: this is the solution chosen by Waytoplay, Brio, and almost all other competitors.

From experience with Brio tracks, M/M or F/F adapters are a constraint, and I do not intend to print my support on both sides: I naturally choose hermaphroditic tabs, which are male and female at the same time.

Laser Cutting

Living not far from a very good fablab, I will take my license on the Laser System 1490 cutter/engraver. This makes the cutting of the tabs feasible, and I also take the opportunity to cut the tiles to the shape of the printed roads rather than keeping the "blanks."

Improvement of Road Traces

I take the opportunity to improve the tight turn and parking tiles. I add "chicane" tiles and abandon the "bridge" tile. The source files for printing and cutting are free and downloadable right here:

The Result

The result is even better. The tiles hold together perfectly but remain very easy to assemble/separate. The close-cut tracing gives a Waytoplay-like appearance.

Completed Puzzle Roads v2

But there are (inevitably) new problems:

Maybe I will improve these points in v3!
