I designed these traffic signs based on the official documentation of the National Road Safety Directorate of the Argentine Republic, the country where I live.

In this first stage, I design the Preventive Signs, they are in the shape of a yellow diamond, with a black border. There are a total of 38 different signs.
The complete sign design is made in 3 parts, the base, the border and the sign itself. Both the border and the sign are printed in black, and the diamond base is printed in yellow. These colors are the official ones, although it goes in each one if you want to make your own decorative version from now on.
There are 2 types of bases:
- The normal model has a cutout in the back to be able to fit the post there and thus have a complete traffic sign.
- The model with a ring allows you to use any of these signals as a key ring.
Within each type of base there are 3 models (1,2 and 3) that are identical in dimensions and whose only difference is the pin or pins added to embed the signal in the correct place.
Base 1 (1 pin in the center), used for the following signals: 1,2,3,4,5,6,7,8,9,13,18,19,21,22,24,25,26 ,27,28,29,30,31,32,33,34,35,36,37,38
Base 2 (2 pins), used for the following signals: 10,11,12,15,16,17,23
Base 3 (1 pin moved from center), used for the following signals: 14,20
The design of the pins and the corresponding holes in the signals to embed are for reference only, any of which can be used for any signal, since they can simply be cut by hand due to their small size. Given the small size, a good calibration of the printer is necessary so that the diameter of the pin and the hole fit together without problem.
Signals 18,19,20 and 21 have loose parts that do not fit into the pins and must necessarily be glued with a drop of glue.
All signs can be glued on with a bead of glue to ensure they don't come off their pin.
The borders are printed in black, they fit nicely on the base and the use of glue is not needed, although it can be added if necessary of course.

The post and its base fit together without the need for glue, and are printed without supports. Pay attention to the orientation of the post, it must be with the box raised up, that will be the one that fits into the back of the base of the sign. The recommendation is to print them in grey, resembling metal.

The author marked this model as their own original creation.
