This is part of the series of 30 exercises developed during the E3D+VET program. The aim of this Erasmus+ program is the immersion in 3D printing of VET centres (website: https://www.e3dplusvet.eu/).

There are 12 models of composite geometric bodies. There are 6 different composite geometric bodies, each once are labeled with Braille (embossed) and another with black text (bright model, so that the font stands out well). The models 5 and 6 consist of two parts.

For Braille (computer or 8 point Braille) please note the following sizes:
A Braille character with its maximum of six (or eight) points is called a shape.
The size of the palpable Braille characters is 6 to 7 mm, the following dimensions are common:

• point distances 2.5 mm
• point thickness 1.5 mm (diameter)
• form distances 6 mm
• line spacing 10 mm
• point height (elevation) at least 0.4 mm (optimal height 0.5 - 0.7 mm)

An appropriate font I send with (EURO 800.ttf).

The script must either be printed sublimely and painted with a black pen or printed in two colors.
The color of the Braille models does not matter.
The models with black text should be printed in light colour so that the lettering stands out well.
