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/).

The exercise is composed by 3 geometrical pieces with different shapes and difficulty levels:

• Piece 1, easy level
• Piece 2, medium level
• Piece 3, hard level

These pieces can be stored by putting them together forming a cube.
