  • the diameter D1 is for example 5.45 mm ⁇ 0.1.
  • the edges adjacent to the end face 31 can be at least partially chamfered to facilitate the passage of a connecting element 7 intended to be positioned in the recesses as will be described in more detail in the following description.
  • the chamfer 310 may in particular comprise portions 320 slightly concave at the level of the lateral faces 33, 35, 37 and 39 to form a guide and facilitate the passage of the connecting element 7.

Material withdrawals can be made between forms 73 ′ of the second type and the bottom of the internal contour.
  • the width L1 of the internal contour at the level of the material recesses is for example greater than the diameter of the cross section of the crosspieces 1 while the width L2 'at the level of the forms 73' of the second type is substantially less than the diameter of the cross section of the cross sections of so as to form a housing making it possible to receive and maintain a crosspiece inside the internal contours of the two walls 7a and 7b as represented by the dotted circle of diameter D3.

  • the connecting elements 7 are for example made of plastic from biomass
  • connection elements 7 constitute the basic elements of the construction set and alone allow a large number of connections and therefore the possibility of obtaining a wide variety of constructions. In addition, certain connections allow relative movement between the parts which makes it possible to obtain mobile constructions.
  • the figures 9 and 10 represent examples of possible construction from the construction set. In the example of the figure 9 , only the basic elements are used for the construction while in the example of the figure 10 , additional elements (wheels, headlight) are used.
  • the connecting elements 7 and the end pieces 3 allow a large number of connections from two types of simple parts.
  • the connections obtained by these elements do not require a severe tolerance at the manufacturing level so that these elements can be produced from mechanically less efficient materials, for example materials whose ratio between the Young's modulus ( in MPa) and the limiting stress (in MPa) is less than 0.024, for example 0.015 such as plastics from biomass.
  • the sleepers 1 can also be made of plastic from biomass or wood, which makes it possible to obtain a construction set which is simple to manufacture and whose harmful impact on the environment is reduced compared to the construction sets of the state of the art.
